A double-precision IEEE number is stored in memory address X (see the code in lab_2.s). Write a sequence of MIPS instructions to divide the floating number at X by (-8), prints out the result and store the result back at X. Accomplish this without using any floating-point instructions (assume that overflow doesnt occur). See the code in lab_2.s to move the double-precision floating-point number to integer registers.

There is "YOUR CODE GOES HERE" part
