Title: Division

Grade: 4-a Lesson: S2-L2

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

Examples:

Divide 666 ÷ 18

Step 1a

Divide 549 by 9

Draw the division symbol ⟌ and write divisor 18 is on left side and dividend 666 closed under this symbol.

$1a$

Explanation: Arrange the numbers in division form.

Step 1b

66 is divisible by 18 but since, 18 × 3 = 54. we go for it. subtract 66 - 54 = 12 and write 3 in Quotient.

$1b$

Explanation: Here, the first digit of the dividend is 64, 64 is divisible by 16. Subtract 64 - 64 = 0 and write quotient is 4.

Step 1c

Now, bring down the next value to 6.
The number to be considered now is 126.
126 is not divisible by 18 but since 18 × 7 = 126, subtract 126 - 126 = 0,and write 7 in the Quotient.
Therefore 18 ÷ 7 = 120.

$1c$

Explanation: In this step, bring down the next value, 6, and write it next to 126. Since 126 is divisible by 18, we divide 126 by 18 to get 0 and then subtract 126 from 126, resulting in 0. Hence, 126 divided by 18 is 0.
