We look at the division of 80927631 by 661 
Our goal is to divide 80927631 by 661.

On to step 1:
The number 661 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 661

Moving on to step 2:
When dividing 80 by 661, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 661

On to step 3:
If we divide 809 by 661, we get 1 and a remainder of 148.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 661 from 809 and we're left with 148.
Bring next digit (2) of the dividend behind the 148 and repeat the process: 1482 / 661

Moving on to step 4:
1482 divided by 661 is 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1322 from 1482, we get 160.
Grab the next digit (7) from the dividend, add it to 160, then carry on: 1607 / 661

Advancing to step 5:
661 goes into 1607 2 times with a remainder of 285.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 1322 from 1607, we get 285.
Take the next digit (6) from the dividend and append it to 285, then repeat: 2856 / 661

Going ahead to step 6:
The number 661 fits into 2856 4 times, leaving a remainder of 212.
The number 4 becomes the next digit in our result. 
Result so far: 1224.0
If we subtract 2644 from 2856, we get 212.
Include the next digit (3) from the dividend after 212, then repeat: 2123 / 661

Going ahead to step 7:
661 can be fit into 2123 3 times, resulting in a remainder of 140.
The next digit of our result is 3. 
Result so far: 12243.0
Subtracting 1983 from 2123 leaves us with 140.
Grab the next digit (1) from the dividend, add it to 140, then carry on: 1401 / 661

On to step 8:
661 goes into 1401 2 times with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 122432.0
Subtracting 1322 from 1401 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
If we divide 790 by 661, we get 1 and a remainder of 129.
The next digit of our result is 1. 
Result so far: 122432.1
Subtracting 661 from 790 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 10:
1290 divided by 661 is 1 with a remainder of 629.
The next digit of our result is 1. 
Result so far: 122432.11
If we subtract 661 from 1290, we get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

After the division, we end up with 122432.11 and a remainder of 0.629.
