Let's divide 258718 by 28
The aim is to understand the frequency of 28 in 258718.

Going ahead to step 1:
28 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 28

Advancing to step 2:
The number 28 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 28

On to step 3:
28 goes into 258 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 6 after subtracting 252 from 258.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 28

Advancing to step 4:
28 can be fit into 67 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtracting 56 from 67 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 28

On to step 5:
If we divide 111 by 28, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 923.0
If we take 84 away from 111, we end up with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 28

Advancing to step 6:
278 divided by 28 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9239.0
Subtract 252 from 278 to get 26.
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 7:
When dividing 260 by 28, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9239.9
The remainder is 8 after subtracting 252 from 260.
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 8:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9239.92
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.

On to step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 9239.928
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.

Let's proceed to step 10:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 9239.9285
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.

Step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 9239.92857
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 12:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 9239.928571
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 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9239.9285714
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.

On to step 14:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 9239.92857142
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.

In conclusion, the division gives 9239.92857142 with a balance of 2.4e-08.
