858865 ÷ 28 
Let's see how many times 28 fits into 858865.

On to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 28

Going ahead to step 2:
28 can be fit into 85 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 1 after subtracting 84 from 85.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 28

Going ahead to step 3:
18 divided by 28 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 28

Going ahead to step 4:
28 can be fit into 188 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 306.0
Deduct 168 from 188 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 28

Advancing to step 5:
206 divided by 28 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3067.0
If we subtract 196 from 206, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 28

Step 6:
105 divided by 28 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 30673.0
Deduct 84 from 105 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
28 goes into 210 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 30673.7
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
If we divide 140 by 28, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 30673.75
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.

Moving on to step 9:
If we divide 0 by 28, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30673.75
Deduct 0 from 0 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.

Moving on to step 10:
If we divide 0 by 28, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30673.75
Deduct 0 from 0 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.

After the division, we end up with 30673.75 and a remainder of 0.0.
