We're dividing 99609 by 99 
The aim is to understand the frequency of 99 in 99609.

Moving on to step 1:
99 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 99

Advancing to step 2:
If we divide 99 by 99, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 99 from 99 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 99

Let's proceed to step 3:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 99

Moving on to step 4:
99 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 60 and we're left with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 99

Let's proceed to step 5:
When dividing 609 by 99, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
If we take 594 away from 609, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
The number 99 fits into 150 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1006.1
If we take 99 away from 150, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
When dividing 510 by 99, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1006.15
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
When dividing 150 by 99, we get 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1006.151
Subtract 99 from 150 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
When dividing 510 by 99, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1006.1515
If we subtract 495 from 510, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
99 can be fit into 150 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1006.15151
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
The number 99 fits into 510 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1006.151515
If we subtract 495 from 510, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 99, we get 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1006.1515151
Subtracting 99 from 150 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 13:
If we divide 510 by 99, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1006.15151515
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 1006.15151515 with a balance of 1.5e-08.
