Let's divide 805913 by 99
The aim is to understand the frequency of 99 in 805913.

Moving on to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 99

Step 2:
80 divided by 99 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 99

On to step 3:
The number 99 fits into 805 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 792 away from 805, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 99

On to step 4:
When dividing 139 by 99, we get 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 99 away from 139, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 99

Going ahead to step 5:
401 divided by 99 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 814.0
The remainder is 5 after subtracting 396 from 401.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 99

Going ahead to step 6:
The number 99 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 8140.0
If we subtract 0 from 53, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
When dividing 530 by 99, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 8140.5
The remainder is 35 after subtracting 495 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
350 divided by 99 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 8140.53
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
When dividing 530 by 99, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8140.535
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
99 can be fit into 350 3 times, resulting in a remainder of 53.
The next digit of our result is 3. 
Result so far: 8140.5353
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
When dividing 530 by 99, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8140.53535
The remainder is 35 after subtracting 495 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
99 goes into 350 3 times with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 8140.535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
99 goes into 530 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8140.5353535
Subtracting 495 from 530 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
350 divided by 99 is 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 8140.53535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 8140.53535353 with a balance of 5.3e-08.
