## What Is Division In Math

Math Antics – Division With Partial Quotients

In maths, we have four basic arithmetic operations i.e., addition, subtraction, multiplication, and division. Amongst these four operations, the division is one of the major operations we use in our daily activities. It is the process of splitting a large group into equal smaller groups. For example, divide 25 by 5. Division fact for this example will be, 25 ÷ 5 = 5.

## How To Divide Decimals

Dividing decimals is also as easy as dividing any other numbers. All you need to do is multiply the with powers of ten till you get an integer. Then you can carry out the normal division process. Once you get your final answer, make sure to divide it with the same powers of 10 that you divided earlier with.

## The Formal Written Method Of Long Division

Long division is very similar to short division, but it usually involves dividing larger numbers. Year 6 pupils will learn how to use it when dividing numbers up to 4 digits by a two-digit whole number.

Our explains how to use this method in 9 steps. Included are examples and support resources such as games, worksheets and challenge cards to aid your teaching on the topic.

You might also find useful the below, which can be a great addition to your classroom displays. Or, encourage your little one to use the posters as a visual aid when completing independent tasks and need a bit of a reminder.

We hope you enjoy teaching and learning all about division in maths with our handy resources!

## Division In Different Contexts

Euclidean division is the mathematical formulation of the outcome of the usual process of division of integers. It asserts that, given two integers, a, the dividend, and b, the divisor, such that b â 0, there are unique integers q, the quotient, and r, the remainder, such that a = bq + r and 0 â¤ r< |b|, where |b| denotes the absolute value of b.

## How To Find The Remainder In Division The steps to long division with a remainder are easy to recall using the mnemonic : Does McDonalds Sell Cheese Burgers Daily?:

• Does = Divide
• McDonalds = Multiply
• Sell = Subtract
• Cheese = Compare
• Burgers Daily = Bring Down

If a difference remains after completing all five steps with all the digits of the dividend, that difference is the remainder.

## Some Quick Rules About Division:

• When you divide 0 by another number the answer is always 0. For example: 0 ÷ 2 = 0. That is 0 sweets shared equally among 2 children – each child gets 0 sweets.

• When you divide a number by 0 you are not dividing at all . 2 ÷ 0 is not possible. You have 2 sweets but no children to divide them among. You cannot divide by 0.

• When you divide by 1, the answer is the same as the number you were dividing. 2 ÷ 1 = 2. Two sweets divided by one child.

• When you divide by 2 you are halving the number. 2 ÷ 2 = 1.

• Any number divided by the same number is 1. 20 ÷ 20 = 1. Twenty sweets divided by twenty children – each child gets one sweet.

• Numbers must be divided in the correct order. 10 ÷ 2 = 5 whereas 2 ÷ 10 = 0.2. Ten sweets divided by two children is very different to 2 sweets divided by 10 children.

• All fractions such as ½, ¼ and ¾ are division sums. ½ is 1 ÷ 2. One sweet divided by two children. See our page Fractions for more information.

## How To Divide Whole Numbers By Decimals:

3 divided by .04

1. Multiply the divisor by 10:

.04 × 10 = .4

2. This still isn’t a whole number, so we’ll do it once more:

.4 × 10 = 4

3. Now we want to do the same thing to the dividend:

3 × 10 = 30

4. Because we multiplied the divisor by 10 twice, we’ll do the same to the dividend:

30 × 10 = 300

5. Now 3 divided by .04 has turned into:

300divided by 4

## Dividing A Decimal By A Decimal

In order to divide a decimal by another decimal, we follow the following steps

1. Multiply the dividend and the divisor by 10 or 100 or 1000 etc. to convert the divisor into a whole number.

2. Divide the new dividend by the whole number obtained in the previous step.

Let us understand it by an example.

Suppose we want to divide 3.28 by 0.4

We have, 32.8 / 4 = x = 32.8/4

Now, 32.8 ÷ 4 = 8.2

## Maths: Division Of Decimals

In Year 5, children will also learn how to divide .

The most important rule for dividing decimals is to make the divisor a whole number. This can be done by multiplying the divisor by 10, although for each time you multiply the divisor, you must also multiply the dividend.

Dont worry, well show you how this is done in practice with the example below.

## Division To Find The Solution To Everyday Problems

We use division to find solutions to everyday problems, though at times we dont even recognize it. Suppose we have a total of 488 school students who are to be seated in an auditorium. One row of the auditorium can seat 15 students. How many rows will be fully occupied by the students?

This is a classic example where we use division to find a solution. There are 488 school students and one row can accommodate 15 students. In order to find out how many rows will be required, we need to divide 488 by 15.

So, there would be 32 fully occupied rows and one row that would be partially occupied.

In order to divide a decimal by 10, the decimal point is shifted to the left by one place.

For instance, if we divide 12.68 by10, the result would be 1.268.

In order to divide a decimal by 100, the decimal point is shifted to the left by two places.

For instance, if we divide 1275.7 by100, the result would be 12.757

In order to divide a decimal by 1000, the decimal point is shifted to the left by three places.

For instance, if we divide 32.256 by1000, the result would be 0.032256

Note that if there are no more digits on the left side of the number, we must add 0 to the left as done above.

The following steps are involved when dividing a decimal by a whole number

Check the whole number part of the dividend.

If the whole number part of the dividend is less than the divisor, then place a 0 in the ones place in the quotient. Else, move to the next step.

Let us understand this by an example.

## How To Divide Numbers • When a number is divided by 1, the quotient is the number itself.

Example: 45 ÷ 1= 45.

• The quotient is 1 if a number is divided by itself.

Example: 5 ÷ 5 = 1

• In the division of any negative or positive number by zero, the result is always undefined. It is therefore meaningless to divide any number by 0.

Example: 2 ÷ 0 = Undefined

• The division of zero by any positive or negative number gives zero as the quotient.

Example: 0 ÷ 2 = 0

• The decimal point is moved to the left in the division of any number by another number in multiples of 10, 100, 1000, etc.

Example: 5 ÷ 10 = 0.5 and 5 ÷ 1000 = 0.005

• Positive number / Positive number = Positive quotient

Negative number / Negative number = Positive quotient

Negative number / Positive number = Negative quotient

Positive number / Negative number = Negative quotient

## Division Of Natural Numbers

Division is one of the four basic arithmetic operations in mathematics. It is the opposite operation of multiplication and means splitting something into equal groups. The symbols for division are \$/\$, \$÷\$ and \$:\$ .

The division of two numbers has the following form:

dividend \$:\$ divisor = quotient.

The first number is called the dividend, the second is the divisor and result is called the quotient. We can divide any number by any number except zero. The division by zero is undefined. To be good at dividing numbers you need to have a good knowledge about the division table. The division table is something like an inverse multiplication table.

#### What divides evenly into 32?

The factors of 32 are all the integers that divide 32 without any remainder, and they are 1, 2, 4, 8, 16, and 32.

What does it mean to divide a number evenly?

To divide evenly means that one number can be divided by another without anything left over. In other words no remainder! But 7 cannot be evenly divided by 2, as there will be one left over. Note: evenly in this case means fairly or exactly, it has nothing to do with even numbers, for example 15 can be evenly divided by 3

Can a number that divides into another exactly?

A number that divides evenly into another number is called a factor. Can a factor divide a number exactly? Yes, by definition a factor divides a number exactly Is a number into which a given number divides exactly a multiple?

## How To Write A Remainder

There are different ways you can write the remainder of a division problem. The remainder can be a whole number or faction. You always write the remainder after a capitalized R to signify that it is the remainder.

If you want to express the remainder as something other than a whole number leftover, you can make it into a fraction of the dividend.

Knowing how to write a remainder as a fraction is very easy. The remainder becomes the numerator, and the divisor is the denominator. The unit for the quotient and remainder is named by the dividend and divisor . Simplify the fraction if possible.

## S Of Division: Know Definition Formula Notes & Examples

Learn the Meaning of Dividing Decimals – 

Methods of Division: The meaning of division is to separate a number into two or more equal parts, classes, areas, groups, and categories. In simple words, the meaning of division is to distribute the whole number to a group in equal parts or make equal parts. Let us suppose a diagonal of a rectangle divides it into two equal triangles. The result of a division may or may not be an integer always. Sometimes, the result of division will be in the form of a fraction or decimal.

The way of dividing something is called a method of division. The methods of division are of three types according to the difficulty level. These are the chunking method or division by repeated subtraction, short division method or bus stop method and long division method. This article will cover one of the most important arithmetic operations called Division or Divide and its methods in detail.

## Terminology Used In Division

Terminology means term. There are four important terms used in division. These are dividend, divisor, quotient and remainder.

Dividend: The number to be divided by another number is called the dividend.

Divisor: The number by which we divide another number into equal parts is called the divisor.

Quotient: The result of division is called a quotient.

Remainder: The leftover number after division is called the remainder.

The pictorial representation of the above terminology is given below.

## How To Do Division

One-digit division can be done using multiplication tables. For example, to solve 24 ÷ 6, we just need to see what we need to multiply by 6 to get 24 as the answer. Clearly, 6 × 4 = 24, therefore 24 ÷ 6 = 4. When it comes to the division of numbers with greater numbers, then we can use the long division method. Let us take the example of 65 divided by 5 to understand it. Follow the steps below to learn how to do division:

• Step 1: Draw the division symbol and write divisor on its left side and dividend enclosed under this symbol.
• Step 2: Take the first digit of the dividend from the left . Check if this digit is greater than or equal to the divisor.
• Step 3: Then divide it by the divisor and write the answer on top as the quotient. Here, the quotient of 6 ÷ 5 is 1.
• Step 4: Subtract the product of the divisor and the digit written in the quotient from the first digit of the dividend and write the difference below. Here, the difference is 6 – 5 = 1.
• Step 5: Bring down the next digit of the dividend . The next digit in the dividend is 5.
• Step 6: Repeat the same process until you get the remainder, less than the divisor.

Look at the image given below showing the above steps of division.

## Example Of Methods Of Division #### Example of chunking method
