We're dividing 857289 by 28 
Let's see how many times 28 fits into 857289.

Moving on to step 1:
28 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 28

Advancing to step 2:
85 divided by 28 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 1 after subtracting 84 from 85.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 28

Let's proceed to step 3:
28 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 28

Going ahead to step 4:
172 divided by 28 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 306.0
Subtracting 168 from 172 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 28

Moving on to step 5:
28 goes into 48 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 3061.0
If we subtract 28 from 48, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 28

Step 6:
28 can be fit into 209 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 30617.0
Subtract 196 from 209 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
28 can be fit into 130 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 30617.4
Subtract 112 from 130 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
When dividing 180 by 28, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 30617.46
If we subtract 168 from 180, we 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 9:
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: 30617.464
Subtracting 112 from 120 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.

Advancing to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 30617.4642
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.

Going ahead to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 30617.46428
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.

Advancing to step 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 30617.464285
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.

Let's proceed to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 30617.4642857
If we subtract 196 from 200, we get 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 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 30617.46428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 30617.46428571, with a leftover of 1.2e-08.
