We look at the division of 813906 by 28 
We're looking to find how many times 28 goes into 813906.

Step 1:
28 goes into 8 0 times with 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 28

On to step 2:
28 goes into 81 2 times with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 25 after subtracting 56 from 81.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 28

On to step 3:
253 divided by 28 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 252 from 253 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 28

Advancing to step 4:
28 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 290.0
If we subtract 0 from 19, we get 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 28

On to step 5:
When dividing 190 by 28, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 2906.0
If we subtract 168 from 190, we get 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 28

On to step 6:
226 divided by 28 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 29068.0
If we take 224 away from 226, we end up 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.

Step 7:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 29068.0
The remainder is 20 after subtracting 0 from 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 8:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 29068.07
Subtract 196 from 200 to 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.

Advancing to step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 29068.071
Deduct 28 from 40 and we're left 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.

On to step 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 29068.0714
Deduct 112 from 120 and we're left 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.

Let's proceed to step 11:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 29068.07142
If we subtract 56 from 80, we 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.

Going ahead to step 12:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 29068.071428
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.

Moving on to step 13:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 29068.0714285
If we take 140 away from 160, 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.

On to step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 29068.07142857
Subtract 196 from 200 to 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.

Our division results in 29068.07142857 with a remaining 4e-09.
