Given an integer n and a number base b, write a function that calculates the number of trailing zeros of the factorial of n when written in base-b.

For example, for and , the function should return 5, because:

>> dec2base(factorial(15),4)

>> '103001313131311200000'

For and , the function should return 4.

>> dec2base(factorial(10),12)

>> '1270000'
