We look at the division of 755415 by 26 
The aim is to understand the frequency of 26 in 755415.

On to step 1:
When dividing 7 by 26, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 26

Going ahead to step 2:
When dividing 75 by 26, we get 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 23 after subtracting 52 from 75.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 26

Moving on to step 3:
If we divide 235 by 26, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 234 away from 235, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 26

Step 4:
26 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 26

On to step 5:
26 can be fit into 141 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 2905.0
If we take 130 away from 141, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 26

Advancing to step 6:
The number 26 fits into 115 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 29054.0
Subtracting 104 from 115 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 26 fits into 110 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 29054.4
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 26 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 29054.42
If we subtract 52 from 60, 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.

Step 9:
80 divided by 26 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 29054.423
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
26 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 29054.423
If we subtract 0 from 20, we 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.

Let's proceed to step 11:
26 can be fit into 200 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 29054.42307
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.

On to step 12:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 29054.423076
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.

On to step 13:
When dividing 240 by 26, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 29054.4230769
Subtract 234 from 240 to get 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 14:
When dividing 60 by 26, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 29054.42307692
The remainder is 8 after subtracting 52 from 60.
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 29054.42307692 and a remainder of 8e-09.
