# 2.3 Division of whole numbers  (Page 3/3)

 Page 3 / 3

## Sample set d

Use a calculator to perform each division.

$\text{328}÷8$

 Type 328 Press ÷ Type 8 Press =

$\text{53},\text{136}÷\text{82}$

 Type 53136 Press ÷ Type 82 Press =

$\text{730},\text{019},\text{001}÷\text{326}$

We first try to enter 730,019,001 but find that we can only enter 73001900. If our calculator has only an eight-digit display (as most nonscientific calculators do), we will be unable to use the calculator to perform this division.

$\text{3727}÷\text{49}$

 Type 3727 Press ÷ Type 49 Press =

This number is an example of a decimal number (see [link] ). When a decimal number results in a calculator division, we can conclude that the division produces a remainder.

## Practice set d

Use a calculator to perform each division.

$3,\text{330}÷\text{74}$

45

$\text{63},\text{365}÷\text{115}$

551

$\text{21},\text{996},\text{385},\text{287}÷\text{53}$

Since the dividend has more than eight digits, this division cannot be performed on most nonscientific calculators. On others, the answer is 415,026,137.4

$4,\text{558}÷\text{67}$

This division results in 68.02985075, a decimal number, and therefore, we cannot, at this time, find the value of the remainder. Later, we will discuss decimal numbers.

## Exercises

For the following problems, perform the divisions.

The first 38 problems can be checked with a calculator by multiplying the divisor and quotient then adding the remainder.
