We look at the division of 640032 by 8 
We're looking to find how many times 8 goes into 640032.

Going ahead to step 1:
8 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 8

Moving on to step 2:
8 can be fit into 64 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 64 from 64 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 8

Advancing to step 3:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 8

Step 4:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
If we subtract 0 from 0, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 8

Moving on to step 5:
If we divide 3 by 8, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 8000.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 8

Advancing to step 6:
If we divide 32 by 8, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 80004.0
Deduct 32 from 32 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80004.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 80004.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 80004.0, and the remainder is 0.0.
