Divide Whole Numbers


Division is used to separate objects into equal groups.

Dividend ÷ Divisor = Quotient

 

Key Terms

If you multiply the quotient by the divisor, its product will be the dividend. (Multiplication is an inverse operation of division.)

24÷4=6 because 6 (quotient) x 4 (divisor) = 24 (dividend)


 

Example



Here are some important quotients and properties of division:


Important Quotients

Any number, except zero, divided by itself is 1.

8÷8=1


Any number divided by 1 is that number.

27÷1=27


Properties of Zero in Division

Zero divided by any other number is zero.

0÷7=0

 

Division by zero is not allowed.

7÷0       cannot be performed


There is no number whose product with 0 is 7.

 

Other Ways to Express Division

42 divided by 7 equals 6

   42 / 7 = 6

   427=6


When the dividend is a larger whole number, the digits in the quotient are found in steps. It is possible to check the answer using multiplication.

 

Example 

Divide 844 by 5 and check.



 

Division with Remainders

Sometimes it is not possible to separate objects into a whole number of equal groups. In these cases, a few items will be left over, or remaining.
