815536 divided by 26 
The aim is to understand the frequency of 26 in 815536.

Going ahead to step 1:
8 divided by 26 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 26

Moving on to step 2:
26 goes into 81 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 78 from 81 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 26

Advancing to step 3:
26 can be fit into 35 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 26 from 35 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 26

Going ahead to step 4:
26 goes into 95 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
If we take 78 away from 95, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 26

Step 5:
173 divided by 26 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 3136.0
The remainder is 17 after subtracting 156 from 173.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 26

Moving on to step 6:
If we divide 176 by 26, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 31366.0
Subtract 156 from 176 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.

Advancing to step 7:
200 divided by 26 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 31366.7
Subtracting 182 from 200 leaves us with 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:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 31366.76
If we take 156 away from 180, we end up 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.

Step 9:
26 can be fit into 240 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 31366.769
If we take 234 away from 240, we end up 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.

On to step 10:
If we divide 60 by 26, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 31366.7692
If we take 52 away from 60, we end up 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.

Let's proceed to step 11:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 31366.76923
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
If we divide 20 by 26, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 31366.76923
Subtract 0 from 20 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 13:
When dividing 200 by 26, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 31366.7692307
If we subtract 182 from 200, we 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.

Let's proceed to step 14:
When dividing 180 by 26, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 31366.76923076
If we subtract 156 from 180, 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.

In conclusion, the division gives 31366.76923076 with a balance of 2.4e-08.
