We divide 108088 by 28
The aim is to understand the frequency of 28 in 108088.

Going ahead to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 28

On to step 2:
If we divide 10 by 28, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 28

Step 3:
28 goes into 108 3 times with a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 84 from 108 leaves us with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 28

Step 4:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 38.0
The remainder is 16 after subtracting 224 from 240.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 28

Let's proceed to step 5:
28 can be fit into 168 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
If we take 168 away from 168, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 28

Advancing to step 6:
If we divide 8 by 28, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 3860.0
Deduct 0 from 8 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.

Advancing to step 7:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3860.2
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.

On to step 8:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3860.28
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 9:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3860.285
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 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3860.2857
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.

Moving on to step 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 3860.28571
Deduct 28 from 40 and we're left 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.

Advancing to step 12:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3860.285714
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.

On to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 3860.2857142
Subtracting 56 from 80 leaves us with 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 14:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3860.28571428
Subtracting 224 from 240 leaves us 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.

The final outcome is 3860.28571428, with a leftover of 1.6e-08.
