We look at the division of 8120652 by 660 
Let's see how many times 660 fits into 8120652.

On to step 1:
If we divide 8 by 660, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 660

Let's proceed to step 2:
660 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 660

On to step 3:
660 can be fit into 812 1 times, resulting in a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 660 from 812 leaves us with 152.
Append the next digit (0) from the dividend to 152 and continue with: 1520 / 660

Let's proceed to step 4:
660 goes into 1520 2 times with a remainder of 200.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1320 away from 1520, we end up with 200.
Fetch the next digit (6) from the dividend, attach it to 200 and continue: 2006 / 660

On to step 5:
If we divide 2006 by 660, we get 3 and a remainder of 26.
The next digit of our result is 3. 
Result so far: 123.0
Subtract 1980 from 2006 to get 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 660

Advancing to step 6:
When dividing 265 by 660, we get 0 with a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 1230.0
Subtracting 0 from 265 leaves us with 265.
Include the next digit (2) from the dividend after 265, then repeat: 2652 / 660

Step 7:
If we divide 2652 by 660, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 12304.0
Subtract 2640 from 2652 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 660 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 12304.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
When dividing 1200 by 660, we get 1 with a remainder of 540.
Use 1 as the next digit of our solution. 
Result so far: 12304.01
Deduct 660 from 1200 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 10:
When dividing 5400 by 660, we get 8 with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 12304.018
If we take 5280 away from 5400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
1200 divided by 660 is 1 with a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 12304.0181
Subtracting 660 from 1200 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 12:
5400 divided by 660 is 8 with a remainder of 120.
The next digit of our result is 8. 
Result so far: 12304.01818
If we take 5280 away from 5400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
1200 divided by 660 is 1 with a remainder of 540.
The next digit of our result is 1. 
Result so far: 12304.018181
If we take 660 away from 1200, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 14:
When dividing 5400 by 660, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 12304.0181818
If we subtract 5280 from 5400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
If we divide 1200 by 660, we get 1 and a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 12304.01818181
If we subtract 660 from 1200, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 12304.01818181 and a remainder of 5.4e-07.
