Fix possible internal overflow in numeric division. div_var_fast() postpones propagating carries in the same way as mul_var(), so it has the same corner-case overflow risk we fixed in 246693e5ae8a36f0, namely that the size of the carries has to be accounted for when setting the threshold for executing a carry propagation step. We've not devised a test case illustrating the brokenness, but the required fix seems clear enough. Like the previous fix, back-patch to all active branches.
