513956 divided by 99 
The aim is to understand the frequency of 99 in 513956.

Going ahead to step 1:
5 divided by 99 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 99

Step 2:
99 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 99

Moving on to step 3:
The number 99 fits into 513 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 495 from 513 to get 18.

The next digit of our result is 4. 
Result so far: 5191.474
Subtracting 396 from 470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 5191.4747
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 11:
99 goes into 470 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 5191.47474
Subtracting 396 from 470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
When dividing 740 by 99, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 5191.474747
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
The number 99 fits into 470 4 times, leaving a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 5191.4747474
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
If we divide 740 by 99, we get 7 and a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 5191.47474747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.
