We look at the division of 688668 by 28 
We want to divide 688668 by 28.

Step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 28

Advancing to step 2:
28 goes into 68 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 56 from 68 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 28

On to step 3:
The number 28 fits into 128 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 24.0
If we take 112 away from 128, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 28

Moving on to step 4:
When dividing 166 by 28, we get 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
The remainder is 26 after subtracting 140 from 166.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 28

On to step 5:
28 can be fit into 266 9 times, resulting in a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 2459.0
Deduct 252 from 266 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 28

On to step 6:
148 divided by 28 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 24595.0
If we subtract 140 from 148, we 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 7:
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: 24595.2
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
240 divided by 28 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 24595.28
Deduct 224 from 240 and we're left with 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:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 24595.285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 24595.2857
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:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 24595.28571
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.

On to step 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 24595.285714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 24595.2857142
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.

Let's proceed to step 14:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 24595.28571428
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.

Our division results in 24595.28571428 with a remaining 1.6e-08.
