We divide 221 by 99
The aim is to understand the frequency of 99 in 221.

Moving on to step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 99

Let's proceed to step 2:
When dividing 22 by 99, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 99

Let's proceed to step 3:
If we divide 221 by 99, we get 2 and a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 198 from 221 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 4:
230 divided by 99 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2.2
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 5:
If we divide 320 by 99, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 2.23
Subtracting 297 from 320 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 6:
The number 99 fits into 230 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.232
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
99 can be fit into 320 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 2.2323
Subtract 297 from 320 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
99 goes into 230 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.23232
If we subtract 198 from 230, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
99 goes into 320 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 2.232323
The remainder is 23 after subtracting 297 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
230 divided by 99 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.2323232
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
When dividing 320 by 99, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 2.23232323
Subtract 297 from 320 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 2.23232323 with a remaining 2.3e-08.
