239498 divided by 99 
The aim is to understand the frequency of 99 in 239498.

Advancing to step 1:
99 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 99

Let's proceed to step 2:
When dividing 23 by 99, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 99

Advancing to step 3:
If we divide 239 by 99, we get 2 and a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 198 from 239 and we're left with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 99

Step 4:
The number 99 fits into 414 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 396 from 414, we get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 99

Going ahead to step 5:
99 can be fit into 189 1 times, resulting in a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 241.0
Subtract 99 from 189 to get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 99

On to step 6:
99 can be fit into 908 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 2419.0
Subtracting 891 from 908 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 2419.1
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
The number 99 fits into 710 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 2419.17
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2419.171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
The number 99 fits into 710 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2419.1717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
When dividing 170 by 99, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2419.17171
Subtract 99 from 170 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
710 divided by 99 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 2419.171717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
99 goes into 170 1 times with a remainder of 71.
The next digit of our result is 1. 
Result so far: 2419.1717171
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
If we divide 710 by 99, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 2419.17171717
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 2419.17171717 and a remainder of 1.7e-08.
