We look at the division of 510255 by 28 
The aim is to understand the frequency of 28 in 510255.

Moving on to step 1:
28 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 28

Step 2:
If we divide 51 by 28, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 23 after subtracting 28 from 51.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 28

On to step 3:
When dividing 230 by 28, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 224 from 230 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 28

Step 4:
28 goes into 62 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 182.0
If we take 56 away from 62, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 28

Advancing to step 5:
When dividing 65 by 28, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 1822.0
If we take 56 away from 65, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 28

Let's proceed to step 6:
If we divide 95 by 28, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 18223.0
The remainder is 11 after subtracting 84 from 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 18223.3
The remainder is 26 after subtracting 84 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 28, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 18223.39
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.

Moving on 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: 18223.392
Deduct 56 from 80 and we're left 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.

On to step 10:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18223.3928
Subtract 224 from 240 to 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.

Advancing to step 11:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 18223.39285
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.

Going ahead to step 12:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 18223.392857
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.

On to step 13:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 18223.3928571
If we subtract 28 from 40, 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.

Moving on to step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18223.39285714
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.

In conclusion, the division gives 18223.39285714 with a balance of 8e-09.
