476509 ÷ 99 
The aim is to understand the frequency of 99 in 476509.

Advancing to step 1:
99 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 99

Advancing to step 2:
The number 99 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 99

Moving on to step 3:
99 can be fit into 476 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 396 from 476 leaves us with 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 99

Step 4:
99 goes into 805 8 times with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 792 away from 805, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 99

Let's proceed to step 5:
If we divide 130 by 99, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
Deduct 99 from 130 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 99

Let's proceed to step 6:
319 divided by 99 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 4813.0
Subtracting 297 from 319 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
99 can be fit into 220 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 4813.2
Subtracting 198 from 220 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
99 goes into 220 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 4813.22
If we take 198 away from 220, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 4813.22 with a balance of 0.022.
