26112 ÷ 91 
The aim is to understand the frequency of 91 in 26112.

Advancing to step 1:
91 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 91

Moving on to step 2:
26 divided by 91 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 91

Step 3:
91 goes into 261 2 times with a remainder of 79.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 182 away from 261, we end up with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 91

Advancing to step 4:
If we divide 791 by 91, we get 8 and a remainder of 63.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 728 from 791 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 91

Step 5:
91 goes into 632 6 times with a remainder of 86.
The next digit of our result is 6. 
Result so far: 286.0
If we take 546 away from 632, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 6:
The number 91 fits into 860 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 286.9
Subtract 819 from 860 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
410 divided by 91 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 286.94
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
91 goes into 460 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 286.945
If we subtract 455 from 460, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 91, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 286.945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 91 fits into 500 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 286.94505
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
When dividing 450 by 91, we get 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 286.945054
The remainder is 86 after subtracting 364 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
When dividing 860 by 91, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 286.9450549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
91 can be fit into 410 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 286.94505494
If we subtract 364 from 410, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 286.94505494, with a leftover of 4.6e-08.
