We look at the division of 842397 by 28 
Let's see how many times 28 fits into 842397.

Advancing to step 1:
If we divide 8 by 28, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 28

Advancing to step 2:
When dividing 84 by 28, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 84 from 84 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 28

Step 3:
The number 28 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 28

Advancing to step 4:
The number 28 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 300.0
If we subtract 0 from 23, we get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 28

Advancing to step 5:
28 can be fit into 239 8 times, resulting in a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 3008.0
If we subtract 224 from 239, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 28

On to step 6:
28 can be fit into 157 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 30085.0
If we subtract 140 from 157, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
28 can be fit into 170 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 30085.6
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
28 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 30085.6
If we take 0 away from 20, we end up 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.

Step 9:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 30085.607
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 30085.6071
Subtract 28 from 40 to 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 11:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 30085.60714
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.

Advancing to step 12:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 30085.607142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 30085.6071428
Subtracting 224 from 240 leaves us 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.

Moving on to step 14:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 30085.60714285
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.

The final outcome is 30085.60714285, with a leftover of 2e-08.
