We look at the division of 687688 by 28 
We're looking to find how many times 28 goes into 687688.

Step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 28

Moving on to step 2:
When dividing 68 by 28, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we take 56 away from 68, we end up with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 28

Step 3:
When dividing 127 by 28, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 112 from 127 leaves us with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 28

Let's proceed to step 4:
28 goes into 156 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 245.0
If we take 140 away from 156, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 28

On to step 5:
28 goes into 168 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2456.0
Deduct 168 from 168 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 28

Advancing to step 6:
If we divide 8 by 28, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 24560.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
28 goes into 80 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 24560.2
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 24560.28
Subtract 224 from 240 to 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.

Step 9:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 24560.285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 24560.2857
Subtracting 196 from 200 leaves us 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.

Moving on to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 24560.28571
Subtract 28 from 40 to get 12.
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 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 24560.285714
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.

Advancing to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 24560.2857142
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 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24560.28571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 24560.28571428, with a leftover of 1.6e-08.
