- 8086 DIV Instruction ( Unsigned Operands) The DIV instruction performs the division of two unsigned operands.
The denominator resides in a source operand and it should not be immediate.
However, it can be register or a memory location. Does assembly have division?
Description. div executes unsigned division. div divides a 16-, 32-, or 64-bit register value (dividend) by a register or memory byte, word, or long (divisor)..
How division works in assembly language?
div executes unsigned division. div divides a 16-, 32-, or 64-bit register value (dividend) by a register or memory byte, word, or long (divisor).
The quotient is stored in the AL, AX, or EAX register respectively.
The remainder is stored in AH, Dx, or EDX..

BSS Section.
Text Section..
How to divide in 8086 assembly?
8086 has DIV instruction to perform division.
Take the 8-bit number into BL, and 16-bit number into AX.
Now divide AX by BL.
The result will be stored at AX..

What is Div and IDIV in assembly language?
The DIV instruction divides unsigned numbers, and IDIV divides signed numbers.
Both return a quotient and a remainder.
Table 4.1 summarizes the division operations.
The dividend is the number to be divided, and the divisor is the number to divide by..
What is div instruction in 8086?
The division process in the 8086 is similar to grade-school long division, except in binary instead of decimal.
The diagram below shows the process: dividing 67 (the dividend) by 9 (the divisor) yields the quotient 7 at the top and the remainder 4 at the bottom..

What is the program of assembly language?
A program written in assembly language consists of a series of mnemonic processor instructions and meta-statements (known variously as declarative operations, directives, pseudo-instructions, pseudo-operations and pseudo-ops), comments and data..
Why are there multiple assembly languages?
Because each processor type's instruction set is unique, assembly languages are necessarily different among processor types.
In the early days of computing, almost everyone programmed in assembly.
It was far easier to work with than any machine language, but still gave the programmer direct access to the CPU..
- A program written in assembly language consists of a series of mnemonic processor instructions and meta-statements (known variously as declarative operations, directives, pseudo-instructions, pseudo-operations and pseudo-ops), comments and data.
- Fast division by 10 on the ARM can be done with this formula: R0 = (R0 * 3277) / 32768.
- The DIV instruction divides unsigned numbers, and IDIV divides signed numbers.
Both return a quotient and a remainder.
Table 4.1 summarizes the division operations.
The dividend is the number to be divided, and the divisor is the number to divide by. - The information about division using a library function is provided for you in case you wonder whether we can perform division in ARM assembler - answer is yes, just not with an assembler instruction, but with a subroutine.
- You can learn the basics in less than two weeks but after that, you will have to make an important decision: For which processor family do you want to learn Assembly?
