The patch below boosts performance of decimal formatting of integers by
roughly a factor of 2 on ARM7 CPU without hardware integer division. In
fact it replaces integer modulo operation with multiply and subtract,
that hopefully is either faster or roughly the same on all supported
CPUs.

I agree. I've applied the patch, thanks!
