We look at the division of 69720453 by 26 
The aim is to understand the frequency of 26 in 69720453.

Advancing to step 1:
26 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 26

Advancing to step 2:
When dividing 69 by 26, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 52 from 69 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 26

On to step 3:
26 can be fit into 177 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 156 from 177 to get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 26

Moving on to step 4:
26 can be fit into 212 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 268.0
Subtract 208 from 212 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 26

Going ahead to step 5:
26 goes into 40 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 2681.0
If we subtract 26 from 40, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 26

Going ahead to step 6:
When dividing 144 by 26, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 26815.0
The remainder is 14 after subtracting 130 from 144.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 26

Moving on to step 7:
26 goes into 145 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 268155.0
The remainder is 15 after subtracting 130 from 145.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 26

Step 8:
26 can be fit into 153 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 2681555.0
If we take 130 away from 153, we end up 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.

Let's proceed to step 9:
26 can be fit into 230 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 2681555.8
The remainder is 22 after subtracting 208 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2681555.88
If we subtract 208 from 220, 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.

Our division results in 2681555.88 with a remaining 0.012.
