We're dividing 357495 by 99 
The aim is to understand the frequency of 99 in 357495.

Moving on to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 99

Advancing to step 2:
The number 99 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 99

Let's proceed to step 3:
357 divided by 99 is 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 297 from 357 leaves us with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 99

Going ahead to step 4:
99 goes into 604 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 594 from 604, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 99

Advancing to step 5:
The number 99 fits into 109 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Deduct 99 from 109 and we're left with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 99

Going ahead to step 6:
99 goes into 105 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 3611.0
If we subtract 99 from 105, 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.

Going ahead to step 7:
99 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3611.0
The remainder is 60 after subtracting 0 from 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 8:
600 divided by 99 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3611.06
Subtracting 594 from 600 leaves us with 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 9:
99 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3611.06
Deduct 0 from 60 and we're left 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.

Step 10:
99 can be fit into 600 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3611.0606
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:
99 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3611.0606
The remainder is 60 after subtracting 0 from 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 12:
When dividing 600 by 99, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 3611.060606
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.

Advancing to step 13:
60 divided by 99 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3611.060606
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
If we divide 600 by 99, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3611.06060606
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.

After the division, we end up with 3611.06060606 and a remainder of 6e-09.
