We look at the division of 607525 by 28 
The aim is to understand the frequency of 28 in 607525.

Step 1:
6 divided by 28 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 28

Going ahead to step 2:
28 goes into 60 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 4 after subtracting 56 from 60.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 28

Step 3:
When dividing 47 by 28, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 28 away from 47, we end up with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 28

On to step 4:
The number 28 fits into 195 6 times, leaving a remainder of 27.
The next digit of our result is 6. 
Result so far: 216.0
Subtract 168 from 195 to get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 28

Let's proceed to step 5:
28 can be fit into 272 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 2169.0
Deduct 252 from 272 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 28

Step 6:
When dividing 205 by 28, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 21697.0
Deduct 196 from 205 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 28 fits into 90 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 21697.3
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 28 fits into 60 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 21697.32
If we subtract 56 from 60, we get 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 9:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 21697.321
The remainder is 12 after subtracting 28 from 40.
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 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 21697.3214
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.

Going ahead to step 11:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 21697.32142
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.

Going ahead to step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 21697.321428
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 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 21697.3214285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 21697.32142857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 21697.32142857 with a balance of 4e-09.
