686127 ÷ 79 
We want to figure out the number of times 686127 can be divided by 79.

Advancing to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 79

On to step 2:
68 divided by 79 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 79

On to step 3:
If we divide 686 by 79, we get 8 and a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 54 after subtracting 632 from 686.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 79

On to step 4:
When dividing 541 by 79, we get 6 with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 474 from 541 leaves us with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 79

Advancing to step 5:
If we divide 672 by 79, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 868.0
Deduct 632 from 672 and we're left with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 79

Going ahead to step 6:
79 can be fit into 407 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 8685.0
The remainder is 12 after subtracting 395 from 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 79, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 8685.1
Deduct 79 from 120 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
79 can be fit into 410 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8685.15
If we subtract 395 from 410, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 79 is 1 with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 8685.151
If we subtract 79 from 150, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
79 can be fit into 710 8 times, resulting in a remainder of 78.
The next digit of our result is 8. 
Result so far: 8685.1518
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
79 goes into 780 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 8685.15189
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
79 can be fit into 690 8 times, resulting in a remainder of 58.
The next digit of our result is 8. 
Result so far: 8685.151898
Subtracting 632 from 690 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
The number 79 fits into 580 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 8685.1518987
Subtracting 553 from 580 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
270 divided by 79 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 8685.15189873
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 8685.15189873 with a remaining 3.3e-08.
