  Description:
 
     Divides an implied destination operand by a specified source
     operand. Both operands are treated as unsigned numbers. If the
     source (divisor) is 16 bits wide, the implied destination
     (dividend) is the DX:AX register pair.
 
     The quotient goes into AX and the remainder into DX. If the
     source is 8 bits wide, the implied destination operand is
     AX. The quotient goes into AL and the remainder into AH. On the
     80386/486, if the source is EAX, the quotient goes into EAX and
     the remainder into EDX.
