We divide 248397 by 99
The aim is to understand the frequency of 99 in 248397.

Going ahead to step 1:
When dividing 2 by 99, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 99

Going ahead to step 2:
99 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 99

On to step 3:
248 divided by 99 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 198 from 248 leaves us with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 99

Moving on to step 4:
The number 99 fits into 503 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 8 after subtracting 495 from 503.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 99

Moving on to step 5:
If we divide 89 by 99, we get 0 and a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
If we take 0 away from 89, we end up with 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 99

On to step 6:
If we divide 897 by 99, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2509.0
Subtract 891 from 897 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 99, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2509.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
600 divided by 99 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 2509.06
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
If we divide 60 by 99, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 2509.06
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
99 goes into 600 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2509.0606
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 99 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 2509.0606
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
99 can be fit into 600 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 2509.060606
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
When dividing 60 by 99, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2509.060606
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
When dividing 600 by 99, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 2509.06060606
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 2509.06060606 with a remainder of 6e-09.
