384257 divided by 99 
The aim is to understand the frequency of 99 in 384257.

Let's proceed to step 1:
3 divided by 99 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 99

Step 2:
99 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 99

Moving on to step 3:
When dividing 384 by 99, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 297 from 384 and we're left with 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 99

Advancing to step 4:
If we divide 872 by 99, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 80 after subtracting 792 from 872.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 99

Step 5:
The number 99 fits into 805 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
If we take 792 away from 805, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 99

Moving on to step 6:
137 divided by 99 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 3881.0

Going ahead to step 9:
99 can be fit into 380 3 times, resulting in a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 3881.383
If we subtract 297 from 380, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
830 divided by 99 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 3881.3838
Subtracting 792 from 830 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
99 goes into 380 3 times with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 3881.38383
If we subtract 297 from 380, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
When dividing 830 by 99, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 3881.383838
Subtract 792 from 830 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
The number 99 fits into 380 3 times, leaving a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 3881.3838383
Subtract 297 from 380 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
99 goes into 830 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 3881.38383838
Subtracting 792 from 830 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.
