Let's divide 205594 by 91
The aim is to understand the frequency of 91 in 205594.

Let's proceed to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 91

On to step 2:
When dividing 20 by 91, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 91

On to step 3:
91 goes into 205 2 times with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 23 after subtracting 182 from 205.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 91

Step 4:
91 goes into 235 2 times with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 53 after subtracting 182 from 235.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 91

Moving on to step 5:
If we divide 539 by 91, we get 5 and a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Subtract 455 from 539 to get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 91

Let's proceed to step 6:
844 divided by 91 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 2259.0
If we subtract 819 from 844, 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.

Advancing to step 7:
If we divide 250 by 91, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2259.2
If we subtract 182 from 250, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 2259.27
Subtract 637 from 680 to get 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 9:
430 divided by 91 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 2259.274
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
660 divided by 91 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2259.2747
If we subtract 637 from 660, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 91, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2259.27472
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.

On to step 12:
91 can be fit into 480 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2259.274725
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
91 can be fit into 250 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2259.2747252
Deduct 182 from 250 and we're left 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.

Moving on to step 14:
91 goes into 680 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 2259.27472527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 2259.27472527 with a remainder of 4.3e-08.
