Here is an Haskell version:

On my system it takes 30 seconds.
You're only dividing integers by integers to get Doubles.
x /. y = fromIntegral x / fromIntegral y
works just fine in this case.
No, this *does not works*.
I get Nan as result, since fromIntegral a, when a is out of range of a
double, returns Infinity.
Prelude> (fromIntegral (fac 777)) :: Double
Infinity
CPython, does not try to convert to double, but, instead, to a scaled
double.
