Title: Division

Grade: 4-a Lesson: S1-L1

Explanation: The best way to understand divisions is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Divide 510 ÷ 2

Step 1a

Draw the division symbol ⟌ and write divisor 2 is on left side and dividend 510 enclosed under this symbol.

$1a$

Explanation: Arrange the numbers in division form.

Step 1b

5 is not divisible by 2, but since 2 × 2 = 4, we proceed with it.
Subtract 5 - 4 = 1 and write 2 in the first quotient.

$1b$

Explanation: In this step, 5 is not divisible by 2. However, since 2 × 2 = 4, we proceed with it. Subtract 5 - 4 = 1 and write 2 in the first quotient.

Step 1c

Now, bring down the next value, 1. The number to be considered now is 11.
11 is not divisible by 2, but since 2 × 5 = 10, subtract 11 - 10 = 1 and write 5 in the Quotient.

$1c$

Explanation: In the next step, bring down the value 1. Since 11 is not divisible by 2, we can subtract the closest multiple of 2, 10, from 11 to get 1, and then write 5 in the Quotient.

Step 1d

Now, bring down the next value to 0.
The number to be considered now is 10.
10 is divisible by 2 but since 2 × 5 = 10, subtract 10 - 10 = 0,and write 5 in the quotient. Therefore 510 ÷ 2 = 255.

$1d$

Explanation: In this step, bring down the next value, 10, and write it next to 0. Since 10 is divisible by 2, we divide 10 by 2 to get 5 and then subtract 10 from 10, resulting in 0. Hence, 510 divided by 2 is 255.
