Parts of division
❖ Dividend : means the number that is being divided.
Ex: 6 ÷ 2 = 3
❖ Divisor : means the number that divides the dividend
or first number.
Ex: 6 ÷ 2 = 3
❖ Quotient : means the answer you get after dividing
1st number by 2nd.
Ex: 6 ÷ 2 = 3
Division facts
Division of any number by 1 ,
the answer is always the
number itself.
Ex- 6 ÷ 1 = 6 , 89 ÷ 1 = 89
Division of any number
by 0, the answer is always
zero.
Ex- 6 ÷ 0 = 0, 89 ÷ 0 = 0
Division of any number by the
number itself, the answer is always
one (1).
Ex- 6 ÷ 6 = 1, 89 ÷ 89 = 1
Different ways to do division
1) Repeated Subtraction:
a) 6 ÷ 2 =
6 - 2 = 4
4 - 2 = 2
2 - 2 = 0
3 steps
3 b) 12 ÷ 3 =
12 - 3 = 9
9 - 3 = 6
6 - 3 = 3
4 steps
4
3 - 3 = 0
c) 12 ÷ 4 =
12 - 4 = 8
8 - 4 = 4
4 - 4 = 0
3 steps
3 d) 20 ÷ 5 =
20 - 5 = 15
15 - 5 =10
10 - 5 = 5
4 steps

5 - 5 = 0

3) Horizontal method:
a) 14 ÷ 2 = 7 b) 18 ÷ 3 = 6
Check/Verify:
2 x 7 = 14
Check/Verify:
3 x 6 = 18
c) 16 ÷ 4 = 4 d) 20 ÷ 5 = 4
Check/Verify:
4 x 4 = 16
Check/Verify:
4 x 5 = 20
e) 40 ÷ 8 = 5 f) 27 ÷ 3 = 9
Check/Verify:
5 x 8 = 40
Check/Verify:
9 x 3 = 27
Solve the following
a) 35 ÷ 5 =
