AX – This is the accumulator. It is of 16 bits and is divided into two 8-bit registers AH and AL to also perform 8-bit instructions. It is generally used for arithmetical and logical instructions but in 8086 microprocessor it is not mandatory to have accumulator as the destination operand.
- Assign value 500 in SI and 600 in DI.
- Move the contents of [SI] in BL and increment SI by 1.
- Move the contents of [SI] and [SI + 1] in AX.
- Use DIV instruction to divide AX by BL.
- Move the contents of AX in [DI].
- Halt the program.
- 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.

Where is the dividend and divisor?
When we divide two numbers, the number that is being divided is the dividend, whereas the number by which we divide is the divisor. For example, 12 candies are to be divided among 3 children. So we have 12 ÷ 3. Here, 12 is the dividend, and 3 is the divisor.
