We're dividing 812363 by 28 
The aim is to understand the frequency of 28 in 812363.

Step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 28

On to step 2:
When dividing 81 by 28, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 56 from 81 to get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 28

Let's proceed to step 3:
When dividing 252 by 28, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 252 from 252, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 28

Advancing to step 4:
28 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 28

On to step 5:
28 can be fit into 36 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 2901.0
Deduct 28 from 36 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 28

Going ahead to step 6:
28 can be fit into 83 2 times, resulting in a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 29012.0
If we subtract 56 from 83, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 28 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 29012.9
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 28 fits into 180 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 29012.96
Subtract 168 from 180 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.

Step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 29012.964
If we take 112 away from 120, we end up 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 10:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 29012.9642
If we take 56 away from 80, we end up 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.

Advancing to step 11:
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: 29012.96428
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.

On to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 29012.964285
Deduct 140 from 160 and we're left 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.

Advancing to step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 29012.9642857
Subtracting 196 from 200 leaves us with 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 14:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 29012.96428571
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.

In conclusion, the division gives 29012.96428571 with a balance of 1.2e-08.
