We're dividing 510270 by 28 
The aim is to understand the frequency of 28 in 510270.

Moving on to step 1:
5 divided by 28 is 0 with a remainder of 5.
The next digit of our result is 0. 
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

Going ahead to step 2:
The number 28 fits into 51 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 28 from 51 to get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 28

Let's proceed to step 3:
The number 28 fits into 230 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 224 from 230 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 28

Moving on to step 4:
28 can be fit into 62 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 182.0
Subtract 56 from 62 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 28

Moving on to step 5:
28 can be fit into 67 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 1822.0
If we subtract 56 from 67, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 28

Let's proceed to step 6:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 18223.0
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.

Advancing to step 7:
28 goes into 260 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 18223.9
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 8:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 18223.92
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 18223.928
If we take 224 away from 240, we end up 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.

Step 10:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 18223.9285
Subtract 140 from 160 to 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.

Moving on to step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 18223.92857
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.

On to step 12:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 18223.928571
Subtracting 28 from 40 leaves us 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.

Going ahead to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 18223.9285714
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 14:
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: 18223.92857142
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.

In conclusion, the division gives 18223.92857142 with a balance of 2.4e-08.
