We look at the division of 208660 by 28 
The aim is to understand the frequency of 28 in 208660.

Let's proceed to step 1:
When dividing 2 by 28, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 28

Let's proceed to step 2:
28 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 28

On to step 3:
If we divide 208 by 28, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 12 after subtracting 196 from 208.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 28

Let's proceed to step 4:
28 goes into 126 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we take 112 away from 126, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 28

Moving on to step 5:
When dividing 146 by 28, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
If we take 140 away from 146, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 28

Step 6:
28 goes into 60 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7452.0
Subtract 56 from 60 to 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.

Advancing to step 7:
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: 7452.1
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.

Let's proceed to step 8:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 7452.14
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7452.142
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.

Let's proceed to step 10:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7452.1428
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.

Moving on to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 7452.14285
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 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7452.142857
Deduct 196 from 200 and we're left 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 13:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 7452.1428571
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.

Let's proceed to step 14:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7452.14285714
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.

After the division, we end up with 7452.14285714 and a remainder of 8e-09.
