We look at the division of 274151 by 99 
The aim is to understand the frequency of 99 in 274151.

Going ahead to step 1:
99 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 99

Advancing to step 2:
If we divide 27 by 99, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 99

Step 3:
99 goes into 274 2 times with a remainder of 76.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 198 from 274 leaves us with 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 99

Advancing to step 4:
The number 99 fits into 761 7 times, leaving a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 693 from 761, we get 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 99

Going ahead to step 5:
If we divide 685 by 99, we get 6 and a remainder of 91.
Record the quotient 6 as the next digit in the result. 
Result so far: 276.0
Subtract 594 from 685 to get 91.
Fetch the next digit (1) from the dividend, attach it to 91 and continue: 911 / 99

Advancing to step 6:
If we divide 911 by 99, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 2769.0
The remainder is 20 after subtracting 891 from 911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 99, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2769.2
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 99, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2769.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
99 goes into 200 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2769.202
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
99 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2769.202
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 99 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2769.20202
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
20 divided by 99 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2769.20202
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 99 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2769.2020202
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
When dividing 20 by 99, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2769.2020202
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2769.2020202, with a leftover of 2e-08.
