Division is where you find how many times one number is in another number. It is a short method of subtraction. Dividing 30 by 6 is a way of finding the number of times 6 is contained in 30. The following subtractions show 30 ÷ 6.
30 – 6 = 24
24 – 6 = 18
18 – 6 = 12
12 – 6 = 6
6 – 6 = 0
Six is subtracted 5 times from 30. So, there are 5 sixes contained in 30.
30 ÷ 6 = 5
