We look at the division of 80232715 by 660 
Let's see how many times 660 fits into 80232715.

Step 1:
When dividing 8 by 660, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 660

Moving on to step 2:
When dividing 80 by 660, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 660

Let's proceed to step 3:
The number 660 fits into 802 1 times, leaving a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 660 from 802 leaves us with 142.
Grab the next digit (3) from the dividend, add it to 142, then carry on: 1423 / 660

On to step 4:
When dividing 1423 by 660, we get 2 with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1320 from 1423 leaves us with 103.
Fetch the next digit (2) from the dividend, attach it to 103 and continue: 1032 / 660

Step 5:
When dividing 1032 by 660, we get 1 with a remainder of 372.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
The remainder is 372 after subtracting 660 from 1032.
Bring next digit (7) of the dividend behind the 372 and repeat the process: 3727 / 660

Advancing to step 6:
660 can be fit into 3727 5 times, resulting in a remainder of 427.
Use 5 as the next digit of our solution. 
Result so far: 1215.0
Deduct 3300 from 3727 and we're left with 427.
Grab the next digit (1) from the dividend, add it to 427, then carry on: 4271 / 660

Step 7:
660 can be fit into 4271 6 times, resulting in a remainder of 311.
Put 6 as the next digit of the answer. 
Result so far: 12156.0
If we subtract 3960 from 4271, we get 311.
Fetch the next digit (5) from the dividend, attach it to 311 and continue: 3115 / 660

Advancing to step 8:
3115 divided by 660 is 4 with a remainder of 475.
Put 4 as the next digit of the answer. 
Result so far: 121564.0
Deduct 2640 from 3115 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 9:
4750 divided by 660 is 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 121564.7
Subtracting 4620 from 4750 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
660 goes into 1300 1 times with a remainder of 640.
The number 1 becomes the next digit in our result. 
Result so far: 121564.71
Subtracting 660 from 1300 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 11:
When dividing 6400 by 660, we get 9 with a remainder of 460.
Put 9 as the next digit of the answer. 
Result so far: 121564.719
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
If we divide 4600 by 660, we get 6 and a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 121564.7196
If we take 3960 away from 4600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
6400 divided by 660 is 9 with a remainder of 460.
The number 9 becomes the next digit in our result. 
Result so far: 121564.71969
If we subtract 5940 from 6400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 14:
4600 divided by 660 is 6 with a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 121564.719696
The remainder is 640 after subtracting 3960 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 15:
If we divide 6400 by 660, we get 9 and a remainder of 460.
The next digit of our result is 9. 
Result so far: 121564.7196969
If we subtract 5940 from 6400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
660 goes into 4600 6 times with a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 121564.71969696
If we take 3960 away from 4600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 121564.71969696 with a remaining 6.4e-07.
