We look at the division of 202676 by 91 
The aim is to understand the frequency of 91 in 202676.

On to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 91

Moving on to step 2:
The number 91 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 91

Advancing to step 3:
When dividing 202 by 91, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 182 from 202, we get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 91

Let's proceed to step 4:
When dividing 206 by 91, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 24 after subtracting 182 from 206.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 91

Let's proceed to step 5:
91 goes into 247 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 222.0
If we subtract 182 from 247, we get 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 91

Step 6:
If we divide 656 by 91, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 2227.0
If we subtract 637 from 656, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 91, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2227.2
Deduct 182 from 190 and we're left 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.

Advancing to step 8:
91 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 2227.2
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
800 divided by 91 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 2227.208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
91 can be fit into 720 7 times, resulting in a remainder of 83.
The next digit of our result is 7. 
Result so far: 2227.2087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 11:
91 goes into 830 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2227.20879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
91 goes into 110 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2227.208791
Subtract 91 from 110 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 91 fits into 190 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2227.2087912
If we subtract 182 from 190, 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.

Going ahead to step 14:
If we divide 80 by 91, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 2227.2087912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 2227.2087912, with a leftover of 8e-08.
