The problem code is fctr i think

def numzero(num):
        sum = 0
        n = 0
        while int(num) >= int(5**n) :
                n+=1
                sum = sum + math.floor((num/(5**n)).real)
        return sum
counter = 0
cases = raw_input()
list = []
while counter < int(cases):
        n = raw_input()
        list.append(numzero(int(n)))
        counter = counter + 1
counter = 0
while counter < int(cases):
        print int(list[counter])
