We're dividing 239211 by 20 
Our goal is to divide 239211 by 20.

Advancing to step 1:
2 divided by 20 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

Moving on to step 2:
20 can be fit into 23 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 20 from 23 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 20

Let's proceed to step 3:
When dividing 39 by 20, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 20 from 39 to get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 20

On to step 4:
192 divided by 20 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 180 from 192 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 20

Going ahead to step 5:
20 goes into 121 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 1196.0
If we take 120 away from 121, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 20

Let's proceed to step 6:
When dividing 11 by 20, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 11960.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11960.5
If we subtract 100 from 110, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11960.55
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11960.55 with a remainder of 0.0.
