No so. Any number system that includes zero

can have the equivalent of the decimal system.

For example, if your base 5 system's digits are

0,1,2,3,4 (instead of 1,2,3,4,5), you can do

long division and square root calculations in it

exactly the same way as in our familiar base 10

system (whose digits are 0,1,2,3,4,5,6,7,8,9).

If you can't see how, I'll happily show you.
