We look at the division of 227430 by 99 
The aim is to understand the frequency of 99 in 227430.

Going ahead to step 1:
2 divided by 99 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 99

Advancing to step 2:
99 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 99

Step 3:
99 can be fit into 227 2 times, resulting in a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 198 from 227 and we're left with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 99

On to step 4:
If we divide 294 by 99, we get 2 and a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 198 away from 294, we end up with 96.
Bring next digit (3) of the dividend behind the 96 and repeat the process: 963 / 99

Going ahead to step 5:
If we divide 963 by 99, we get 9 and a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 229.0
Deduct 891 from 963 and we're left with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 99

Going ahead to step 6:
The number 99 fits into 720 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 2297.0
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
When dividing 270 by 99, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 2297.2
If we subtract 198 from 270, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
720 divided by 99 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2297.27
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
99 goes into 270 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 2297.272
Subtract 198 from 270 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
If we divide 720 by 99, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 2297.2727
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
99 goes into 270 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2297.27272
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
720 divided by 99 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 2297.272727
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
The number 99 fits into 270 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 2297.2727272
If we subtract 198 from 270, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
If we divide 720 by 99, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 2297.27272727
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 2297.27272727 and a remainder of 2.7e-08.
