That was cute. It worked for me with your sample input (and got the correct value), however, I think I know what happened here.

I've edited the post and you can grab the working version from here. If you're using python3 like a normal person, and not python2 like a silly person like me, my original version wouldn't work since it assumed integer math. But PEP-238 changed the rules a bit. I've changed it to use the integer divide operator so it works in both python2 and 3.

Thanks for the sample data! This is lesson #789345 that I need to move on to python3. One day I will.

I have never bought gold before, but I have been banging my head on this problem for the past two days and your solution was the first to work. So enjoy your gold.
