We're dividing 274661 by 91 
The aim is to understand the frequency of 91 in 274661.

On to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 91

Let's proceed to step 2:
91 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 91

Going ahead to step 3:
91 can be fit into 274 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 273 away from 274, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 91

Advancing to step 4:
When dividing 16 by 91, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 91

Advancing to step 5:
91 can be fit into 166 1 times, resulting in a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 301.0
Deduct 91 from 166 and we're left with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 91

Going ahead to step 6:
If we divide 751 by 91, we get 8 and a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 3018.0
Subtracting 728 from 751 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
91 goes into 230 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 3018.2
If we subtract 182 from 230, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
91 goes into 480 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3018.25
If we subtract 455 from 480, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 91, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 3018.252
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 3018.2527
Deduct 637 from 680 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
When dividing 430 by 91, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 3018.25274
Subtract 364 from 430 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
91 goes into 660 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 3018.252747
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 91, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 3018.2527472
Deduct 182 from 230 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
When dividing 480 by 91, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3018.25274725
If we subtract 455 from 480, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 3018.25274725 with a remaining 2.5e-08.
