We look at the division of 80120826 by 660 
Let's see how many times 660 fits into 80120826.

On to step 1:
When dividing 8 by 660, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 660

Going ahead to step 2:
660 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 660

On to step 3:
660 goes into 801 1 times with a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 660 from 801 to get 141.
Include the next digit (2) from the dividend after 141, then repeat: 1412 / 660

Let's proceed to step 4:
If we divide 1412 by 660, we get 2 and a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1320 from 1412 and we're left with 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 660

Going ahead to step 5:
660 can be fit into 920 1 times, resulting in a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we subtract 660 from 920, we get 260.
Include the next digit (8) from the dividend after 260, then repeat: 2608 / 660

On to step 6:
660 goes into 2608 3 times with a remainder of 628.
Write down 3 as next digit of the result. 
Result so far: 1213.0
Deduct 1980 from 2608 and we're left with 628.
Include the next digit (2) from the dividend after 628, then repeat: 6282 / 660

Advancing to step 7:
When dividing 6282 by 660, we get 9 with a remainder of 342.
Put 9 as the next digit of the answer. 
Result so far: 12139.0
Subtracting 5940 from 6282 leaves us with 342.
Grab the next digit (6) from the dividend, add it to 342, then carry on: 3426 / 660

Let's proceed to step 8:
When dividing 3426 by 660, we get 5 with a remainder of 126.
Put 5 as the next digit of the answer. 
Result so far: 121395.0
The remainder is 126 after subtracting 3300 from 3426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
If we divide 1260 by 660, we get 1 and a remainder of 600.
Use 1 as the next digit of our solution. 
Result so far: 121395.1
Deduct 660 from 1260 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 10:
When dividing 6000 by 660, we get 9 with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 121395.19
Subtracting 5940 from 6000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
660 goes into 600 0 times with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 121395.19
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
660 can be fit into 6000 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 121395.1909
Deduct 5940 from 6000 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
The number 660 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 121395.1909
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
6000 divided by 660 is 9 with a remainder of 60.
The next digit of our result is 9. 
Result so far: 121395.190909
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
600 divided by 660 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 121395.190909
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 16:
6000 divided by 660 is 9 with a remainder of 60.
The next digit of our result is 9. 
Result so far: 121395.19090909
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 121395.19090909 with a balance of 6e-08.
