We're dividing 20120 by 99 
Our goal is to divide 20120 by 99.

Advancing to step 1:
When dividing 2 by 99, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 99

Advancing to step 2:
When dividing 20 by 99, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 99

Let's proceed to step 3:
If we divide 201 by 99, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 198 from 201 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 99

Step 4:
99 goes into 32 0 times with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 32 after subtracting 0 from 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 99

Going ahead to step 5:
320 divided by 99 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 203.0
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.

Advancing to step 6:
If we divide 230 by 99, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 203.2
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.

Let's proceed to step 7:
When dividing 320 by 99, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 203.23
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.

Moving on to step 8:
If we divide 230 by 99, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 203.232
Subtracting 198 from 230 leaves us 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.

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: 203.2323
Deduct 297 from 320 and we're left 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.

Advancing to step 10:
99 goes into 230 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 203.23232
Deduct 198 from 230 and we're left 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.

Advancing to step 11:
The number 99 fits into 320 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 203.232323
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.

Step 12:
When dividing 230 by 99, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 203.2323232
Deduct 198 from 230 and we're left 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.

Let's proceed to step 13:
99 goes into 320 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 203.23232323
If we take 297 away from 320, we end up 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.

In conclusion, the division gives 203.23232323 with a balance of 2.3e-08.
