Interestingly I do this backwards which means forwards;

I divide by 10,000, print the integer part ascii offset (save the remainder for next step, then by 1000 (print as before), by 100 (again print..), by 10 (print..) and just ascii offset the remainder. In fact since i have to work with 32 and 24 bit values this extends to those widths.
