We divide 812557 by 28
The aim is to understand the frequency of 28 in 812557.

Going ahead 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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 28

Advancing to step 2:
If we divide 81 by 28, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 56 from 81 leaves us with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 28

Advancing to step 3:
If we divide 252 by 28, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 252 away from 252, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 28

Let's proceed to step 4:
When dividing 5 by 28, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 28

Going ahead to step 5:
55 divided by 28 is 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 2901.0
If we subtract 28 from 55, we get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 28

Let's proceed to step 6:
28 goes into 277 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 29019.0
The remainder is 25 after subtracting 252 from 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
28 goes into 250 8 times with a remainder of 26.
The next digit of our result is 8. 
Result so far: 29019.8
The remainder is 26 after subtracting 224 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
28 can be fit into 260 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 29019.89
If we take 252 away from 260, 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.

Going ahead to step 9:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 29019.892
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.

Going ahead to step 10:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 29019.8928
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 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 29019.89285
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.

Going ahead to step 12:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 29019.892857
If we take 196 away from 200, we end up 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.

Let's proceed to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 29019.8928571
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 14:
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: 29019.89285714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 29019.89285714 with a remainder of 8e-09.
