# 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.

are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
