*1 0 0 word (AH) / byte (AL)
quotient → byte (AL) remainder → byte (AH)
*2 1 0 word (A) / byte (ear)
quotient → byte (A) remainder → byte (ear)
*3 0 *6 word (A) / byte (eam)
quotient → byte (A) remainder → byte (eam)
*4 1 0 long (A) / word (ear)
quotient → word (A) remainder → word (ear)
*5 0 *7 long (A) / word (eam)
quotient → word (A) remainder → word (eam)
byte (AH) * byte (AL) → word (A)
