Division by 10 means splitting a total quantity into 10 equal groups or finding how many groups of 10 are in a number. When you divide by 10, each group gets the same amount.
Dividing by 10 is the opposite, or inverse, operation of multiplying by 10. If you know your 10s multiplication facts, you can use them to help you divide.
Dividing a whole number by 10 has a special pattern that can help you find the answer quickly.
This pattern works because our number system is base-ten. Removing a zero is like moving the digits one place value to the right.
Memorizing these basic facts will make dividing by 10 fast and easy. These are the facts you will use most often.
Notice the pattern: the quotient (answer) is the first digit(s) of the dividend (without 0). For 80 ÷ 10, the quotient is 8. For 120 ÷ 10, the quotient is 12.
Understanding division helps solve everyday problems, like sharing items or organizing things into equal sets.
When you see a problem involving splitting something into 10 parts or making groups of 10, it's a signal to divide by 10.
