0-12V Digital Display? Answered

Here's what I need, and haven't been able to figure out how to do it:

I designed a motor speed controller that runs a 12V fan.  Speed control is via PWM through a 50K linear Potentiometer. I need to be able to read the percentage of run voltage ie: 0V=0%, 6V=50%, 12V=100%.  I want to display this on 3 7-segment LED displays.

Anyone with insight would be greatly appreciated.
