Won't this output the digits in reverse order?
Yes it will, but as I mentioned in an off-list message, the use of putchar is probably not very useful for a real-world implementation either, so you can compensate for the order when accumulating the result into a string (or whatever).
I guess as a former hardware guy the heavy stack use for such a trivial purpose just red-flagged me. Old habits die hard ;-)
