I was going to say that divmod was slower because it performs float
division instead of the integer division of // (which is true), but I'm
guessing the slowdown comes from the extra dictionary lookup needed for
divmod (unless this is somehow optimized away) instead. If that's indeed
true, then it seems that divmod doesn't adequately perform its intended
purpose, i.e. make use of the FPU's ability to divide and modulusify in
one step to gain speed.
