Lesson - Divide Whole Numbers
Divide Whole Numbers
Division is used to separate objects into equal groups.
Dividend ÷ Divisor = Quotient
Key Terms
- The dividend is the number that needs to be divided.
- The divisor shows the number of groups into which the dividend needs to be divided.
- The quotient is the answer, or result of the division. It shows the number of objects that will be in each group.
If you multiply the quotient by the divisor, its product will be the dividend. (Multiplication is an inverse operation of division.)
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.
Any number divided by 1 is that number.
Properties of Zero in Division
Zero divided by any other number is zero.
Division by zero is not allowed.
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
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.
