We're dividing 81268 by 91 
The aim is to understand the frequency of 91 in 81268.

Advancing to step 1:
8 divided by 91 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 91

Moving on to step 2:
91 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 91

Moving on to step 3:
The number 91 fits into 812 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 728 from 812 to get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 91

Let's proceed to step 4:
91 goes into 846 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 819 from 846, we get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 91

On to step 5:
91 can be fit into 278 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 893.0
Subtracting 273 from 278 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
91 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 893.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
If we divide 500 by 91, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 893.05
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
The number 91 fits into 450 4 times, leaving a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 893.054
Subtract 364 from 450 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
91 goes into 860 9 times with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 893.0549
Deduct 819 from 860 and we're left with 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 10:
The number 91 fits into 410 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 893.05494
The remainder is 46 after subtracting 364 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 91, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 893.054945
Subtracting 455 from 460 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
The number 91 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 893.054945
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.

Moving on to step 13:
When dividing 500 by 91, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 893.05494505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 893.05494505, with a leftover of 4.5e-08.
