In each place value there are only 10 digits that can be placed, 1,2,3,4,5,6,7,8,9,0.

At that point then next place value is used.

A different place value system in computers is the based two system.

Its number system goes like this

0=0

1=1

10=2

11=3

100=4

Almost exactly like the decimal system, but the base is the number 2, instead of the number 10. This refers to the place-value system: in decimal, each digit has a place-value that is 10 times as much as the digit on the right; in binary, the factor is 2. It is helpful if you understand the place-value system in decimal first.
