We look at the division of 324039 by 28 
The aim is to understand the frequency of 28 in 324039.

Step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 28

Moving on to step 2:
If we divide 32 by 28, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 28 from 32.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 28

Advancing to step 3:
If we divide 44 by 28, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 28 from 44, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 28

Step 4:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 140 from 160, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 28

Step 5:
28 can be fit into 203 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 1157.0
Subtract 196 from 203 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 28

Let's proceed to step 6:
28 goes into 79 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 11572.0
If we take 56 away from 79, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 28 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 11572.8
If we take 224 away from 230, we end up 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.

On to step 8:
When dividing 60 by 28, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 11572.82
Subtracting 56 from 60 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 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 11572.821
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.

Going ahead to step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 11572.8214
Subtract 112 from 120 to 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.

Going ahead to step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 11572.82142
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.

On to step 12:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 11572.821428
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.

Going ahead to step 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 11572.8214285
Deduct 140 from 160 and we're left 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.

Let's proceed to step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 11572.82142857
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.

Our division results in 11572.82142857 with a remaining 4e-09.
