Grade: 4-a Lesson: S1-L2

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

Examples:

Step 1a

Divide 549 by 9

Draw the division symbol ⟌ and write divisor (9) on its left side and dividend (549) enclosed under this symbol.

$1a$

Explanation: Arrange the numbers in division form:

Step 1b

Now 5 < 9 bring down the next digit of the dividend and place it beside 5.
So, we have 54 as the new dividend. 54 is divisible by 9 ,We know that 9 x 6 = 54 so, we go for it.
Write quotient 6 and subtract 54 - 54 = 0.

$1b$

Explanation: So, we have 54 as the new dividend ,divisible by 9, we know that 9 x 6 = 54
Write 6 in the quotient. Subtract: 54 - 54 = 0.

Step 1c

Therefore quotient = 61 and remainder = 0

$1c$

Explanation: The last digit of the dividend is 9 and it is equal to the divisor. So, 9 ÷ 9 = 1. So, 1 is written on top as the quotient.

Therefore quotient is 61 and remainder is 0.
