8792987 ÷ 686 
We want to figure out the number of times 8792987 can be divided by 686.

Advancing to step 1:
When dividing 8 by 686, we get 0 with 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.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 686

On to step 2:
If we divide 87 by 686, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 686

Going ahead to step 3:
If we divide 879 by 686, we get 1 and a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 686 from 879 and we're left with 193.
Include the next digit (2) from the dividend after 193, then repeat: 1932 / 686

Advancing to step 4:
686 can be fit into 1932 2 times, resulting in a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 560 after subtracting 1372 from 1932.
Include the next digit (9) from the dividend after 560, then repeat: 5609 / 686

Going ahead to step 5:
The number 686 fits into 5609 8 times, leaving a remainder of 121.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 5488 from 5609, we get 121.
Grab the next digit (8) from the dividend, add it to 121, then carry on: 1218 / 686

Let's proceed to step 6:
The number 686 fits into 1218 1 times, leaving a remainder of 532.
Put 1 as the next digit of the answer. 
Result so far: 1281.0
Subtracting 686 from 1218 leaves us with 532.
Append the next digit (7) from the dividend to 532 and continue with: 5327 / 686

Step 7:
If we divide 5327 by 686, we get 7 and a remainder of 525.
Record the quotient 7 as the next digit in the result. 
Result so far: 12817.0
If we take 4802 away from 5327, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 8:
The number 686 fits into 5250 7 times, leaving a remainder of 448.
The number 7 becomes the next digit in our result. 
Result so far: 12817.7
Subtract 4802 from 5250 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
If we divide 4480 by 686, we get 6 and a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 12817.76
If we subtract 4116 from 4480, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
When dividing 3640 by 686, we get 5 with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 12817.765
Deduct 3430 from 3640 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
The number 686 fits into 2100 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 12817.7653
If we subtract 2058 from 2100, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
686 goes into 420 0 times with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 12817.7653
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 13:
When dividing 4200 by 686, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 12817.765306
Subtract 4116 from 4200 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
686 can be fit into 840 1 times, resulting in a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 12817.7653061
If we subtract 686 from 840, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 15:
1540 divided by 686 is 2 with a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 12817.76530612
The remainder is 168 after subtracting 1372 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 12817.76530612 with a remainder of 1.68e-07.
