Well - does splitting a number into its digits really teach much about 
mathematics, however it is done? But it's needed for several Euler 
problems, so a reusable way to do it, and do it fast, is useful. I'm not 
sure, by the way, which way is faster (division or converting to a 
string) - probably depends on problem details. So best write functions 
for both methods and keep them.
