120909 divided by 99 
We're looking to find how many times 99 goes into 120909.

On to step 1:
99 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 99

Going ahead to step 2:
If we divide 12 by 99, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 99

Step 3:
99 goes into 120 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 21 after subtracting 99 from 120.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 99

Advancing to step 4:
219 divided by 99 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 21 after subtracting 198 from 219.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 99

Moving on to step 5:
210 divided by 99 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 198 from 210, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 99

Advancing to step 6:
99 can be fit into 129 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
If we subtract 99 from 129, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 1221.3
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1221.3
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
99 can be fit into 300 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1221.303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 99, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1221.303
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 99, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1221.30303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
99 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1221.30303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 99, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1221.3030303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 99, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1221.3030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 1221.3030303 with a balance of 3e-08.
