We're dividing 239212 by 99 
The aim is to understand the frequency of 99 in 239212.

Step 1:
The number 99 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 99

On to step 2:
99 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 99

On to step 3:
When dividing 239 by 99, we get 2 with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 41 after subtracting 198 from 239.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 99

Step 4:
When dividing 412 by 99, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 16 after subtracting 396 from 412.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 99

Let's proceed to step 5:
The number 99 fits into 161 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 241.0
Deduct 99 from 161 and we're left with 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 99

Let's proceed to step 6:
When dividing 622 by 99, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 2416.0
Subtract 594 from 622 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
If we divide 280 by 99, we get 2 and a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 2416.2
Subtract 198 from 280 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 8:
If we divide 820 by 99, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 2416.28
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 99, we get 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 2416.282
If we subtract 198 from 280, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
99 can be fit into 820 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 2416.2828
The remainder is 28 after subtracting 792 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 99, we get 2 with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 2416.28282
If we subtract 198 from 280, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
820 divided by 99 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 2416.282828
Subtracting 792 from 820 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
If we divide 280 by 99, we get 2 and a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 2416.2828282
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
99 goes into 820 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 2416.28282828
If we take 792 away from 820, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 2416.28282828, with a leftover of 2.8e-08.
