688307 divided by 28 
We're looking to find how many times 28 goes into 688307.

Going ahead to step 1:
28 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 28

Going ahead to step 2:
When dividing 68 by 28, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
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

Step 3:
The number 28 fits into 128 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 112 from 128 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 28

Let's proceed to step 4:
163 divided by 28 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
The remainder is 23 after subtracting 140 from 163.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 28

On to step 5:
230 divided by 28 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 2458.0
If we subtract 224 from 230, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 28

Advancing to step 6:
28 goes into 67 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 24582.0
If we subtract 56 from 67, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 24582.3
The remainder is 26 after subtracting 84 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 28, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 24582.39
Subtracting 252 from 260 leaves us 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.

Going ahead to step 9:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 24582.392
Subtracting 56 from 80 leaves us 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.

Moving on to step 10:
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: 24582.3928
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.

On to step 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 24582.39285
Deduct 140 from 160 and we're left 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 12:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 24582.392857
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.

On to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 24582.3928571
If we take 28 away from 40, we end up 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.

Advancing to step 14:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 24582.39285714
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.

The quotient of the division is 24582.39285714, and the remainder is 8e-09.
