Let’s look at dividing 65 by 5.
3
We know that 10 × 5 = 50. 65 is 15 more than 50. We know that 3 × 5 = 15. So there are 13 groups of 5 in 65. We can use what we know about part-whole relationships to help break the number 65 into parts that we can easily divide by 5. We divide 5 tens by 5 and then we divide 15 ones by 5.
65 ÷ 5
10 50 ÷ 5 =
3 15 ÷ 5 =
13
So, 65 ÷ 5 =
1 Use repeated subtraction to divide 48 by 4.

2 Use part-whole relationships to divide 52 by 4.
52 ÷ 4
÷ 4 =
÷ 4 =
So, 52 ÷ 4 =
