Div arm assembly
WebUDIV. Unsigned Divide divides a 32-bit unsigned integer register value by a 32-bit unsigned integer register value, and writes the result to the destination register. The condition flags are not affected. See ARMv7 implementation requirements and options for the divide instructions for more information about this instruction. Encoding T1.
