I don't know what special math modules you're using, but python usually
raises ZeroDivisionError for divide-by-zero problems.

Try printing the intermediate values of each step in your problem code.

d = divide(statistic_array[0,0:4], statistic_array[0,4])
print d

m = multiply(d, 10000.0)
print m

i = int(m)
print i

statistic_array[0,0:4] = i


That might help you track down what's wrong.
