We're dividing 866223 by 28 
We want to divide 866223 by 28.

On to step 1:
8 divided by 28 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 28

On to step 2:
If we divide 86 by 28, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 84 from 86 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 28

On to step 3:
When dividing 26 by 28, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 26 to get 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 28

On to step 4:
262 divided by 28 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 309.0
Deduct 252 from 262 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 28

Moving on to step 5:
The number 28 fits into 102 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3093.0
The remainder is 18 after subtracting 84 from 102.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 28

Going ahead to step 6:
28 goes into 183 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 30936.0
Subtracting 168 from 183 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 28 fits into 150 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 30936.5
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 28, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 30936.53
Deduct 84 from 100 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.

On to step 9:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 30936.535
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.

Going ahead 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: 30936.5357
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.

Advancing to step 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 30936.53571
Subtracting 28 from 40 leaves us 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.

Moving on to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 30936.535714
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.

On to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 30936.5357142
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 14:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 30936.53571428
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 30936.53571428 with a remaining 1.6e-08.
