We're dividing 49863 by 99 
The aim is to understand the frequency of 99 in 49863.

Advancing to step 1:
4 divided by 99 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 99

Going ahead to step 2:
99 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 99

Let's proceed to step 3:
99 goes into 498 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 495 away from 498, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 99

Let's proceed to step 4:
When dividing 36 by 99, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 99

Going ahead to step 5:
99 can be fit into 363 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 503.0
If we subtract 297 from 363, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 6:
If we divide 660 by 99, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 503.6
If we take 594 away from 660, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
If we divide 660 by 99, we get 6 and a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 503.66
Subtract 594 from 660 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 503.66, with a leftover of 0.066.
