Different Ways to do Division


Introduction to division:

Division is the process of frequent subtraction. It can also be described as inverse of multiplication.  Short ways of division is the process  of dividing a group into smaller equal groups.

Different ways to do division:

Division process is performed in different ways to do, such as.

1. Division operation performed through subtraction.

2. Division and number line.

3. Long division.

Now, we are going to learn the above different ways to do division methods.

First Different Ways - Division Operation Performed through Subtraction.

Example:

There are 18 balls and 3 boxes. John wants to put equal number of balls on each bax. How many balls will there be on each table?

Solution:

We have repeatedly subtracted 3 from 18 six times.
That is 18 divided by 3 equals 6.
`(8)/3 = 6`
Thus division is repeated subtraction.
In the division fact `18/3 =6`

Answer:
18 is the dividend       3 is the divisor
6 is the quotient        Here, the remainder is zero.

Second Different Ways - Division and Number Line.

Just as we use the number line for sddition, subtraction, and multiplication, we can use it for division also.

Example:
How many 2's are there in 14?
Solution:

Starting from 14 we can reach 0 by 7 jumps of 2 steps each.
Thus `14 /2 = 7`

Having problem with Double Digit Multiplication Word Problems keep reading my upcoming posts, i will try to help you.

Third Different Ways - Long Division:

Division by a single digit number (without remainder) through long division method.
Example:

Divide 64 by 2.
Solution:

Steps for long division:

1. Arranange the numerals as shown.
2. Divide 6 tens by 2.` 6/2 = 3` Write 3 in tens place in the quotient.Write the product 6 tens (3 x 2 = 6) below the dividend in the tens place. Subtract the product from the dividend.  6 - 6 = 0.
3.  bring down 4 ones. Divide 4 ones by 2. `4/2 =2` ones. Write 2 in ones place in the quotient. Write the product 4 ones (2 x 2 =4) below the dividend in the ones place. Subtract the product from the dividend. 4 -4 = 0

Verification:
Here dividend = 64, divisor = 2, quotient = 32, remainder = 0. We have dividend = (quotient) x (divisor) + remainder.
64 = 32 x 2 + 0

64 = 64

Hence verified.
