=========================================================
divl %ebx

form dividend from edx:eax (edx is the MSL, eax is the LSL)
%ebx is the divisor

after the instruction, %edx is the remainder, %eax is
the quotient


mull %ebx

multiply %ebx and %eax, the product is stored as edx:eax
(edx is the MSL of the product, eax is the LSL of the
product)

n is the number to be printed as a decimal number
while pow10 > 0 do
  print '0'+n / pow10
