We're dividing 865194 by 91 
The aim is to understand the frequency of 91 in 865194.

Advancing to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 91

Going ahead to step 2:
When dividing 86 by 91, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 91

On to step 3:
The number 91 fits into 865 9 times, leaving a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 819 from 865, we get 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 91

On to step 4:
If we divide 461 by 91, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 455 from 461 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 91

Let's proceed to step 5:
91 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 950.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 91

Going ahead to step 6:
91 goes into 694 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 9507.0
Subtracting 637 from 694 leaves us 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 7:
570 divided by 91 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 9507.6
If we subtract 546 from 570, we 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.

Step 8:
91 goes into 240 2 times with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 9507.62
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
When dividing 580 by 91, we get 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 9507.626
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 91 fits into 340 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 9507.6263
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
The number 91 fits into 670 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 9507.62637
Subtracting 637 from 670 leaves us 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.

Advancing to step 12:
When dividing 330 by 91, we get 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 9507.626373
Subtracting 273 from 330 leaves us 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 13:
If we divide 570 by 91, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 9507.6263736
Subtracting 546 from 570 leaves us 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.

Moving on to step 14:
If we divide 240 by 91, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 9507.62637362
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.

The final result is 9507.62637362 with a remainder of 5.8e-08.
