Division

Dividing shares a number out fairly, or finds how many equal groups fit in it: 12 ÷ 3 = 4. It undoes multiplying. When a number doesn't share evenly, what is left over is the remainder, always smaller than the group. You can never divide by zero.

Depth 1 · Foundation

You can divide by sharing or by grouping, check it with multiplying, find a remainder and decide what it means in the question, and know you can't divide by zero.
