195 0/any number
There are eight divisors of the number 195.
There are 12 0s in a trillion - before the decimal point. Since a trillion is a whole number, there is no need for 0s after the decimal point. If you do have 0s after the decimal point, there can by any number that you like and so the question cannot be answered.
If you mean that the number continues by a number of 0s which is one more than the previous numbers of 0s followed by a 2 forever, then it is an irrational number. If you mean that the "2020020002" repeats then it is a rational number.
195 is a not perfect square.
