We look at the division of 13049765 by 99 
The aim is to understand the frequency of 99 in 13049765.

Let's proceed to step 1:
1 divided by 99 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 99

On to step 2:
The number 99 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 99

On to step 3:
99 can be fit into 130 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 31 after subtracting 99 from 130.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 99

On to step 4:
If we divide 314 by 99, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 17 after subtracting 297 from 314.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 99

Step 5:
99 can be fit into 179 1 times, resulting in a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Deduct 99 from 179 and we're left with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 99

Step 6:
The number 99 fits into 807 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 1318.0
Subtract 792 from 807 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 99

On to step 7:
99 goes into 156 1 times with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 13181.0
Deduct 99 from 156 and we're left with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 99

Advancing to step 8:
When dividing 575 by 99, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 131815.0
The remainder is 80 after subtracting 495 from 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
The number 99 fits into 800 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 131815.8
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 99 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 131815.8
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
99 can be fit into 800 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 131815.808
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 99, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 131815.808
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 99 fits into 800 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 131815.80808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
99 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 131815.80808
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
99 goes into 800 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 131815.8080808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 131815.8080808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 131815.8080808, with a leftover of 8e-08.
