We're dividing 282185 by 91 
The aim is to understand the frequency of 91 in 282185.

Going ahead to step 1:
91 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 91

On to step 2:
The number 91 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 91

Advancing to step 3:
282 divided by 91 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 273 from 282 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 91

Let's proceed to step 4:
When dividing 91 by 91, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 0 after subtracting 91 from 91.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 91

Going ahead to step 5:
When dividing 8 by 91, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 310.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 91

Moving on to step 6:
The number 91 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 3100.0
The remainder is 85 after subtracting 0 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
850 divided by 91 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 3100.9
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
310 divided by 91 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 3100.93
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
91 can be fit into 370 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 3100.934
Subtract 364 from 370 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 91 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3100.934
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 91 fits into 600 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 3100.93406
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
If we divide 540 by 91, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 3100.934065
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
If we divide 850 by 91, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 3100.9340659
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
91 can be fit into 310 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 3100.93406593
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 3100.93406593 with a remaining 3.7e-08.
