Your problem is probably in this expression:

> sumFacDigits n `div` 10

Becuase function application binds tightest, this is the same as:

> div (sumFacDigitss n) 10

whereas your original was:

> sumFacDigits (div n 10)

So your transformed program is not the same as your original.

I hope that helps.
