We look at the division of 99101343 by 26 
The aim is to understand the frequency of 26 in 99101343.

Let's proceed to step 1:
9 divided by 26 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 26

Moving on to step 2:
When dividing 99 by 26, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 78 from 99, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 26

Step 3:
26 can be fit into 211 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 3 after subtracting 208 from 211.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 26

Step 4:
The number 26 fits into 30 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 381.0
Subtract 26 from 30 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 26

Moving on to step 5:
26 can be fit into 41 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 3811.0
If we take 26 away from 41, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 26

On to step 6:
153 divided by 26 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 38115.0
If we subtract 130 from 153, we get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 26

Moving on to step 7:
26 goes into 234 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 381159.0
Subtracting 234 from 234 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 26

Advancing to step 8:
When dividing 3 by 26, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 3811590.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 26 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 3811590.1
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
If we divide 40 by 26, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3811590.11
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3811590.11 with a remaining 0.014.
