We divide 935868 by 91
The aim is to understand the frequency of 91 in 935868.

Moving on to step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 91

Going ahead to step 2:
The number 91 fits into 93 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 91 from 93 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 91

On to step 3:
25 divided by 91 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 25, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 91

Let's proceed to step 4:
258 divided by 91 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 76 after subtracting 182 from 258.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 91

Advancing to step 5:
If we divide 766 by 91, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 1028.0
If we subtract 728 from 766, we get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 91

Advancing to step 6:
If we divide 388 by 91, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10284.0
Deduct 364 from 388 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
91 goes into 240 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 10284.2
Subtracting 182 from 240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 10284.26
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
91 can be fit into 340 3 times, resulting in a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 10284.263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
670 divided by 91 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 10284.2637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
When dividing 330 by 91, we get 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 10284.26373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
91 can be fit into 570 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 10284.263736
Subtract 546 from 570 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 91, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 10284.2637362
Subtract 182 from 240 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
91 can be fit into 580 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 10284.26373626
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 10284.26373626 and a remainder of 3.4e-08.
