We're dividing 992126 by 91 
The aim is to understand the frequency of 91 in 992126.

Let's proceed to step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 91

Going ahead to step 2:
If we divide 99 by 91, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 91 from 99 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 91

Step 3:
The number 91 fits into 82 0 times, leaving a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 82, we get 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 91

Step 4:
When dividing 821 by 91, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtracting 819 from 821 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 91

Step 5:
22 divided by 91 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 1090.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 91

Going ahead to step 6:
The number 91 fits into 226 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 10902.0
If we subtract 182 from 226, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
91 goes into 440 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 10902.4
Subtract 364 from 440 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
91 can be fit into 760 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 10902.48
If we subtract 728 from 760, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 91, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 10902.483
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10902.4835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
91 can be fit into 150 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 10902.48351
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
91 goes into 590 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 10902.483516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
When dividing 440 by 91, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 10902.4835164
If we subtract 364 from 440, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
When dividing 760 by 91, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10902.48351648
Subtract 728 from 760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 10902.48351648 and a remainder of 3.2e-08.
