We look at the division of 284836 by 99 
The aim is to understand the frequency of 99 in 284836.

Step 1:
2 divided by 99 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 99

Going ahead to step 2:
99 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 99

Moving on to step 3:
When dividing 284 by 99, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 86 after subtracting 198 from 284.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 99

On to step 4:
If we divide 868 by 99, we get 8 and a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 792 from 868, we get 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 99

Moving on to step 5:
99 goes into 763 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 287.0
If we take 693 away from 763, we end up with 70.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 99

Going ahead to step 6:
99 goes into 706 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2877.0
Deduct 693 from 706 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 99, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 2877.1
Subtracting 99 from 130 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
310 divided by 99 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 2877.13
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 99 fits into 130 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 2877.131
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
When dividing 310 by 99, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 2877.1313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 99 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 2877.13131
If we take 99 away from 130, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 2877.131313
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
If we divide 130 by 99, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 2877.1313131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 2877.13131313
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 2877.13131313 with a balance of 1.3e-08.
