110518 ÷ 91 
The aim is to understand the frequency of 91 in 110518.

Step 1:
1 divided by 91 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 91

Let's proceed to step 2:
The number 91 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 91

Step 3:
The number 91 fits into 110 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 19 after subtracting 91 from 110.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 91

On to step 4:
When dividing 195 by 91, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 13 after subtracting 182 from 195.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 91

Going ahead to step 5:
91 can be fit into 131 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 91 from 131 and we're left with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 91

On to step 6:
When dividing 408 by 91, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 1214.0
If we subtract 364 from 408, 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.

Going ahead to step 7:
440 divided by 91 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1214.4
If we take 364 away from 440, we end up with 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 8:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1214.48
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 1214.483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1214.4835
Deduct 455 from 470 and we're left 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.

Let's proceed to step 11:
150 divided by 91 is 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1214.48351
Subtracting 91 from 150 leaves us 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.

On to step 12:
When dividing 590 by 91, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1214.483516
The remainder is 44 after subtracting 546 from 590.
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 13:
The number 91 fits into 440 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 1214.4835164
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.

Let's proceed to step 14:
760 divided by 91 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1214.48351648
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1214.48351648, with a leftover of 3.2e-08.
