981118 ÷ 91 
The aim is to understand the frequency of 91 in 981118.

Advancing to step 1:
91 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 91

Advancing to step 2:
91 goes into 98 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 91 from 98.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 91

Moving on to step 3:
When dividing 71 by 91, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 91

Let's proceed to step 4:
If we divide 711 by 91, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 637 from 711 leaves us with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 91

Going ahead to step 5:
91 goes into 741 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
If we subtract 728 from 741, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 91

Step 6:
91 goes into 138 1 times with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 10781.0
Subtracting 91 from 138 leaves us with 47.
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 7:
470 divided by 91 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10781.5
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.

Going ahead to step 8:
If we divide 150 by 91, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 10781.51
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 10781.516
Deduct 546 from 590 and we're left with 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 10:
If we divide 440 by 91, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 10781.5164
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.

Moving on to step 11:
760 divided by 91 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 10781.51648
Subtracting 728 from 760 leaves us with 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 12:
91 can be fit into 320 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 10781.516483
If we take 273 away from 320, we end up with 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 13:
91 goes into 470 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10781.5164835
Subtracting 455 from 470 leaves us 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.

Moving on to step 14:
The number 91 fits into 150 1 times, leaving a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 10781.51648351
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.

The final outcome is 10781.51648351, with a leftover of 5.9e-08.
