Hugh Williams did a thorough research of this very question.
Lucas used some 'templates' (which were basically analog mechanisms
for simulating binary arithmetic) to speed the arithmetic. Lucas did
the whole calculation in binary.

I heard Hugh give a talk on this. I believe he also put it in his book.
I would have to go look; I am in the office and the book is at home.
