8. DIV Instruction

• The DIV (unsigned divide) instruction performs 8-bit, 16-bit, and 32-bit division on unsigned integers.

• The instruction formats are:

      DIV reg8/mem8
      DIV reg16/mem16
      DIV reg32/mem32
  

• The single operand is the divisor:

   

    dividend / divisor = quotient ( + remainder )
  

• Quotient is the result of a division. For example, when dividing (7 / 4),

  • the quotient is 1,

  • the remainder after integer division is 3,

  • 7 is called the dividend, and

  • 4 is the divisor.
