203331 ÷ 99 
The aim is to understand the frequency of 99 in 203331.

Step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 99

Going ahead to step 2:
20 divided by 99 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 99

Let's proceed to step 3:
If we divide 203 by 99, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 198 from 203.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 99

Going ahead to step 4:
99 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 53, we get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 99

Going ahead to step 5:
533 divided by 99 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtract 495 from 533 to get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 99

Going ahead to step 6:
99 goes into 381 3 times with a remainder of 84.
The next digit of our result is 3. 
Result so far: 2053.0
Deduct 297 from 381 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 7:
If we divide 840 by 99, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2053.8
Subtracting 792 from 840 leaves us 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.

Step 8:
99 goes into 480 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 2053.84
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
99 goes into 840 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 2053.848
If we take 792 away from 840, we end up 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.

Step 10:
99 goes into 480 4 times with a remainder of 84.
The next digit of our result is 4. 
Result so far: 2053.8484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
99 goes into 840 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2053.84848
The remainder is 48 after subtracting 792 from 840.
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:
99 goes into 480 4 times with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 2053.848484
The remainder is 84 after subtracting 396 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
If we divide 840 by 99, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 2053.8484848
Subtract 792 from 840 to get 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 14:
If we divide 480 by 99, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 2053.84848484
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 2053.84848484, with a leftover of 8.4e-08.
