I've put together a long division calculator that shows the math for remainders or decimal places. I've done some testing on it, but want to work out any kinks that you may find or add enhancements if requested.
This lesson is located on the basic math page, and searchable by division, remainder, long, and decimal. I've tried to design it similar to the mathisfun.com examples in some of the threads here. Enjoy.
