We look at the division of 645152 by 8 
We're looking to find how many times 8 goes into 645152.

Advancing to step 1:
6 divided by 8 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 8

Moving on to step 2:
The number 8 fits into 64 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 64 from 64, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 8

Step 3:
8 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 8

Going ahead to step 4:
8 goes into 51 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 806.0
The remainder is 3 after subtracting 48 from 51.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 8

Advancing to step 5:
If we divide 35 by 8, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 8064.0
The remainder is 3 after subtracting 32 from 35.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 8

Moving on to step 6:
32 divided by 8 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 80644.0
The remainder is 0 after subtracting 32 from 32.
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 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80644.0
Subtracting 0 from 0 leaves us 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.

Advancing to step 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80644.0
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 final result is 80644.0 with a remainder of 0.0.
