835109 divided by 28 
The aim is to understand the frequency of 28 in 835109.

Moving on to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 28

Going ahead to step 2:
28 goes into 83 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 27 after subtracting 56 from 83.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 28

On to step 3:
If we divide 275 by 28, we get 9 and a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 252 from 275 leaves us with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 28

Let's proceed to step 4:
If we divide 231 by 28, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 298.0
If we subtract 224 from 231, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 28

Let's proceed to step 5:
70 divided by 28 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2982.0
If we subtract 56 from 70, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 28

Going ahead to step 6:
The number 28 fits into 149 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 29825.0
If we take 140 away from 149, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 28 fits into 90 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 29825.3
Deduct 84 from 90 and we're left 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.

Step 8:
60 divided by 28 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 29825.32
Deduct 56 from 60 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.

Advancing to step 9:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 29825.321
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.

Going ahead to step 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 29825.3214
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.

Advancing to step 11:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 29825.32142
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.

Going ahead to step 12:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 29825.321428
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.

Step 13:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 29825.3214285
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.

Step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 29825.32142857
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.

The final result is 29825.32142857 with a remainder of 4e-09.
