We're dividing 18220229 by 99 
The aim is to understand the frequency of 99 in 18220229.

Step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 99

Step 2:
When dividing 18 by 99, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 99

On to step 3:
99 goes into 182 1 times with a remainder of 83.
The next digit of our result is 1. 
Result so far: 1.0
If we take 99 away from 182, we end up with 83.
Take the next digit (2) from the dividend and append it to 83, then repeat: 832 / 99

Step 4:
The number 99 fits into 832 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 792 from 832 to get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 99

Moving on to step 5:
99 can be fit into 400 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Deduct 396 from 400 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 99

Step 6:
The number 99 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 1840.0
If we take 0 away from 42, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 99

Moving on to step 7:
422 divided by 99 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 18404.0
Subtracting 396 from 422 leaves us with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 99

On to step 8:
If we divide 269 by 99, we get 2 and a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 184042.0
Subtracting 198 from 269 leaves us 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.

On to step 9:
If we divide 710 by 99, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 184042.7
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.

Advancing to step 10:
When dividing 170 by 99, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 184042.71
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.

Step 11:
When dividing 710 by 99, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 184042.717
Deduct 693 from 710 and we're left 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 12:
99 goes into 170 1 times with a remainder of 71.
The next digit of our result is 1. 
Result so far: 184042.7171
If we take 99 away from 170, we end up 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.

Moving on to step 13:
99 can be fit into 710 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 184042.71717
The remainder is 17 after subtracting 693 from 710.
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 14:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 184042.717171
Subtracting 99 from 170 leaves us 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.

Moving on to step 15:
710 divided by 99 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 184042.7171717
Deduct 693 from 710 and we're left 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 16:
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: 184042.71717171
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.

Our division results in 184042.71717171 with a remaining 7.1e-08.
