868630 ÷ 28 
We want to figure out the number of times 868630 can be divided by 28.

Going ahead to step 1:
If we divide 8 by 28, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 28

Advancing to step 2:
When dividing 86 by 28, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 84 from 86 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 28

Going ahead to step 3:
28 goes into 28 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 28 from 28 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 28

Let's proceed to step 4:
28 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 28

Step 5:
28 can be fit into 63 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 3102.0
If we subtract 56 from 63, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 28

On to step 6:
28 goes into 70 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 31022.0
If we take 56 away from 70, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
28 goes into 140 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31022.5
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
28 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31022.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 28 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31022.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 31022.5 with a remaining 0.0.
