91197 ÷ 26 
The aim is to understand the frequency of 26 in 91197.

Advancing to step 1:
If we divide 9 by 26, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 26

Step 2:
91 divided by 26 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 78 away from 91, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 26

Let's proceed to step 3:
When dividing 131 by 26, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 130 from 131, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 26

On to step 4:
26 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 350.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 26

Step 5:
The number 26 fits into 197 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3507.0
Subtracting 182 from 197 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
26 goes into 150 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3507.5
If we subtract 130 from 150, 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.

Step 7:
When dividing 200 by 26, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 3507.57
If we take 182 away from 200, we end up 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.

Step 8:
26 goes into 180 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3507.576
Subtract 156 from 180 to 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.

Let's proceed to step 9:
240 divided by 26 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 3507.5769
Subtracting 234 from 240 leaves us 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.

Moving on to step 10:
26 goes into 60 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 3507.57692
Subtracting 52 from 60 leaves us 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.

Moving on to step 11:
If we divide 80 by 26, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3507.576923
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
20 divided by 26 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3507.576923
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.

Going ahead to step 13:
When dividing 200 by 26, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 3507.57692307
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.

The final outcome is 3507.57692307, with a leftover of 1.8e-08.
