Let's divide 135117 by 99
The aim is to understand the frequency of 99 in 135117.

Let's proceed to step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 99

Let's proceed to step 2:
99 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 99

Step 3:
135 divided by 99 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 99 from 135, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 99

Going ahead to step 4:
The number 99 fits into 361 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 297 from 361 to get 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 99

Going ahead to step 5:
The number 99 fits into 641 6 times, leaving a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 136.0
The remainder is 47 after subtracting 594 from 641.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 99

Going ahead to step 6:
The number 99 fits into 477 4 times, leaving a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
Deduct 396 from 477 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
If we divide 810 by 99, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1364.8
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 99, we get 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1364.81
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
If we divide 810 by 99, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1364.818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
99 goes into 180 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 1364.8181
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 11:
If we divide 810 by 99, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1364.81818
If we take 792 away from 810, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
99 can be fit into 180 1 times, resulting in a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1364.818181
Deduct 99 from 180 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
The number 99 fits into 810 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1364.8181818
If we take 792 away from 810, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
99 can be fit into 180 1 times, resulting in a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 1364.81818181
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final result is 1364.81818181 with a remainder of 8.1e-08.
