We're dividing 686681 by 28 
Let's see how many times 28 fits into 686681.

Advancing to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 28

Step 2:
When dividing 68 by 28, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 56 from 68, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 28

Going ahead to step 3:
126 divided by 28 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 112 from 126 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 28

On to step 4:
28 can be fit into 146 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 245.0
If we take 140 away from 146, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 28

Moving on to step 5:
28 can be fit into 68 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2452.0
Deduct 56 from 68 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 28

On to step 6:
28 goes into 121 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 24524.0
Subtracting 112 from 121 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 28 fits into 90 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 24524.3
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
28 can be fit into 60 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 24524.32
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 24524.321
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 24524.3214
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 24524.32142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 24524.321428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 24524.3214285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 24524.32142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 24524.32142857, with a leftover of 4e-09.
