220V to 110V converter

Hmmm, I have a 220 in my basement for dryer that I don't need cause the one I have is gas. I was wondering about breaking the 220 down and run to garage for more juice. Now it's 110 at 15 amps. Sounds as though it is a little more involved than just splitting it in half. I am not versed in electric at all, so this is not for me. Thanks to OP for this thread! And thanks to 67Dart273 also for the info.
