Subject: Software that will display partial products

Hello everybody, Does anyone know where I could get software that would display the partial products in a multiplication problem? I am a 7th grade math teacher and I have given a challenge exercise to some of my fast students. It involves a very large multiplication problem. (80 digit product to be exact) After they have it worked out on graph paper I will be displaying their work. I thought it would be really neat if I could somehow print out the entire problem, partial products and all, to go with their posts. Any thoughts or ideas on where I could get something like this? I have scoured the Web and come up with zilch. It seems to me that surely someone had to think about this before I did. Waiting to hear from you.
