Long Division online tool

This very cool tool allows you to work on long division on the computer. It then self corrects the problem. How very cool is this? Division is our next stop with our oldest. We have been using MUS up through this year. It's the only program he likes. But, I'm not sure if we can afford it this next year. So, I've been looking to see what we can come up with. The only thing I want to buy for this year is paper, ink, and a Math Curriculum. I went a little wild last year and I don't feel like we learned anything enjoyable. Nothing much stuck at the very least.

Our oldest has Aspergers and a lot of workbook stuff just really bothers him. So, I'm thinking I might try Math Mammoth since the books are inexpensive along with some fun online games/tools. I think it might fit who is a lot better. He is actually quite intelligent. He understands things the first time you give it to him. So, having to repeat constantly seem beneath him (or at least he feels that way).

But, I'm not good at Math. I'm sure I could be, but I think I need to start over again from the beginning (and thanks to homeschooling my children I get to do just that!)
