This code is inline assembly code in C language that performs division of two integers (a and b) and stores the quotient in a variable called result.

The assembly code first loads the values of a and b into registers eax and ebx, respectively. It then begins a loop labeled CONTD by comparing the value in the ebx register to zero. If ebx is equal to zero, it jumps to DONE; otherwise it continues with the loop.

Within the loop, it clears the edx register, which is typically used to hold the remainder of the division operation, with the XOR instruction. It then divides the value in eax by the value in ebx using the IDIV instruction. The quotient is stored in eax, and the remainder is stored in edx.

The assembly code then moves the value in ebx into eax, and the value in edx into ebx. This swaps the values in the registers so that the value originally in ebx is now in edx and the remainder from the division operation is in ebx.

Finally, the assembly code jumps back to the beginning of the loop at the label CONTD. When ebx eventually becomes zero, the code jumps to the label DONE and stores the final quotient value from eax into the result variable using the MOV instruction.

In summary, this code computes the integer quotient of a/b using inline assembly code within a C program.
