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'
