Let's divide 913317 by 99
The aim is to understand the frequency of 99 in 913317.

Going ahead to step 1:
9 divided by 99 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 99

On to step 2:
91 divided by 99 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 99

Moving on to step 3:
99 goes into 913 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 9.0
If we take 891 away from 913, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 99

Going ahead to step 4:
If we divide 223 by 99, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 198 from 223 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 99

Going ahead to step 5:
99 goes into 251 2 times with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 922.0
If we take 198 away from 251, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 99

Moving on to step 6:
The number 99 fits into 537 5 times, leaving a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 9225.0
If we subtract 495 from 537, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
99 can be fit into 420 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 9225.4
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
If we divide 240 by 99, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 9225.42
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 99, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9225.424
If we take 396 away from 420, we end up 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.

Let's proceed to step 10:
240 divided by 99 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 9225.4242
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
The number 99 fits into 420 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 9225.42424
If we subtract 396 from 420, 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.

Advancing to step 12:
99 goes into 240 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 9225.424242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
When dividing 420 by 99, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9225.4242424
If we take 396 away from 420, we end up 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.

Let's proceed to step 14:
When dividing 240 by 99, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 9225.42424242
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 9225.42424242 with a remaining 4.2e-08.
