Dividing shares a number into equal groups. 20 ÷ 4 asks how many each of 4 groups gets, or how many 4s make 20.

Method 1, share it out: give one counter to each group, and keep going round until none are left.
Count how many each group has. Anything that cannot go round again is the remainder.
Method 2, long division: how many 4s fit? Write it on top, write what you used underneath, subtract, then bring down the next digit. Repeat.

Method 1: Share it out

Share 20 counters between 4 groups, one each at a time, and count what each group gets.

20 ÷ 4

Give one to each of the 4 groups. Keep going round.

Each group gets 5.

20 ÷ 4 = 5

Method 2: Long division

Write 20 inside the bus stop and 4 outside. Work from the left: divide, multiply, subtract, bring down the next digit.

20 ÷ 4

Divide, multiply, subtract, bring down. Repeat for each digit.

20 ÷ 4 = 5
