We're dividing 110809 by 28 
The aim is to understand the frequency of 28 in 110809.

Advancing to step 1:
If we divide 1 by 28, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 28

Going ahead to step 2:
11 divided by 28 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 28

Moving on to step 3:
If we divide 110 by 28, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 26 after subtracting 84 from 110.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 28

Step 4:
268 divided by 28 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 252 from 268 to get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 28

Going ahead to step 5:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
If we take 140 away from 160, we end up with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 28

Going ahead to step 6:
28 goes into 209 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3957.0
Subtracting 196 from 209 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 28, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 3957.4
Subtract 112 from 130 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
28 can be fit into 180 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 3957.46
Subtracting 168 from 180 leaves us 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.

Going ahead to step 9:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 3957.464
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.

Going ahead to step 10:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3957.4642
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.

Advancing to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3957.46428
If we subtract 224 from 240, we 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.

On to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3957.464285
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.

On to step 13:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3957.4642857
Subtracting 196 from 200 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.

Moving on to step 14:
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: 3957.46428571
If we subtract 28 from 40, we 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.

The final result is 3957.46428571 with a remainder of 1.2e-08.
