Let's divide 239565 by 20
Our goal is to divide 239565 by 20.

On to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

On to step 2:
20 goes into 23 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 23 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 20

Step 3:
If we divide 39 by 20, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 11.0
If we take 20 away from 39, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

On to step 4:
When dividing 195 by 20, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 180 from 195 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 20

Moving on to step 5:
20 goes into 156 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1197.0
Subtracting 140 from 156 leaves us with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 20

Let's proceed to step 6:
The number 20 fits into 165 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 11978.0
Subtracting 160 from 165 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
20 can be fit into 50 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 11978.2
If we take 40 away from 50, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead 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: 11978.25
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11978.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11978.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 11978.25 with a balance of 0.0.
