I do now, in fact, divide my mouth into quarters (upper left arcade, upper right arcade, lower right arcade, lower left arcade) - mostly because my electric toothbrush divides its 2-minute runtime into 4 30-second chunks. I think before I had an electric, I used to just do top then bottom (side, side, middle), but it's been a while.
