We divide 8513680 by 691
We're looking to find how many times 691 goes into 8513680.

Advancing to step 1:
691 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 691

Step 2:
85 divided by 691 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 691

Going ahead to step 3:
If we divide 851 by 691, we get 1 and a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 160 after subtracting 691 from 851.
Fetch the next digit (3) from the dividend, attach it to 160 and continue: 1603 / 691

Step 4:
691 goes into 1603 2 times with a remainder of 221.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 221 after subtracting 1382 from 1603.
Include the next digit (6) from the dividend after 221, then repeat: 2216 / 691

On to step 5:
2216 divided by 691 is 3 with a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 2073 from 2216 leaves us with 143.
Take the next digit (8) from the dividend and append it to 143, then repeat: 1438 / 691

Advancing to step 6:
691 can be fit into 1438 2 times, resulting in a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
Subtract 1382 from 1438 to get 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 691

Moving on to step 7:
691 can be fit into 560 0 times, resulting in a remainder of 560.
The next digit of our result is 0. 
Result so far: 12320.0
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 8:
When dividing 5600 by 691, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 12320.8
Subtract 5528 from 5600 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
The number 691 fits into 720 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 12320.81
If we take 691 away from 720, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
691 can be fit into 290 0 times, resulting in a remainder of 290.
The next digit of our result is 0. 
Result so far: 12320.81
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 11:
2900 divided by 691 is 4 with a remainder of 136.
The next digit of our result is 4. 
Result so far: 12320.8104
Subtract 2764 from 2900 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 12:
If we divide 1360 by 691, we get 1 and a remainder of 669.
Write down 1 as next digit of the result. 
Result so far: 12320.81041
Deduct 691 from 1360 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

On to step 13:
When dividing 6690 by 691, we get 9 with a remainder of 471.
The number 9 becomes the next digit in our result. 
Result so far: 12320.810419
The remainder is 471 after subtracting 6219 from 6690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 14:
4710 divided by 691 is 6 with a remainder of 564.
Write down 6 as next digit of the result. 
Result so far: 12320.8104196
Subtract 4146 from 4710 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 15:
5640 divided by 691 is 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 12320.81041968
Subtract 5528 from 5640 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 12320.81041968 with a remainder of 1.12e-07.
