Let's divide 828539 by 26
The aim is to understand the frequency of 26 in 828539.

Going ahead to step 1:
When dividing 8 by 26, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 26

Step 2:
If we divide 82 by 26, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 78 from 82 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 26

On to step 3:
If we divide 48 by 26, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 22 after subtracting 26 from 48.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 26

Moving on to step 4:
26 goes into 225 8 times with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Deduct 208 from 225 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 26

Moving on to step 5:
The number 26 fits into 173 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 3186.0
The remainder is 17 after subtracting 156 from 173.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 26

Step 6:
26 goes into 179 6 times with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 31866.0
Deduct 156 from 179 and we're left 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.

Moving on to step 7:
230 divided by 26 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 31866.8
If we subtract 208 from 230, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 26, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 31866.88
The remainder is 12 after subtracting 208 from 220.
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 31866.88 with a remainder of 0.012.
