325260 divided by 28 
The aim is to understand the frequency of 28 in 325260.

Step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 28

Going ahead to step 2:
If we divide 32 by 28, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 28 from 32 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 28

On to step 3:
If we divide 45 by 28, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 17 after subtracting 28 from 45.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 28

Advancing to step 4:
If we divide 172 by 28, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 116.0
Deduct 168 from 172 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 28

Moving on to step 5:
46 divided by 28 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1161.0
If we take 28 away from 46, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 28

Advancing to step 6:
If we divide 180 by 28, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 11616.0
Subtract 168 from 180 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.

Advancing to step 7:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11616.4
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.

Advancing to step 8:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 11616.42
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.

Advancing to step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 11616.428
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.

Advancing to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 11616.4285
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.

Going ahead to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 11616.42857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 28 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 11616.428571
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.

Moving on to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 11616.4285714
Deduct 112 from 120 and we're left 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: 11616.42857142
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.

The final outcome is 11616.42857142, with a leftover of 2.4e-08.
