239868 divided by 20 
Let's see how many times 20 fits into 239868.

Let's proceed to step 1:
20 can be fit into 2 0 times, resulting in 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.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 20

Step 2:
The number 20 fits into 23 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 23 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 20

Advancing to step 3:
39 divided by 20 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 20 from 39 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 20

Let's proceed to step 4:
The number 20 fits into 198 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we subtract 180 from 198, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 20

Step 5:
If we divide 186 by 20, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1199.0
Deduct 180 from 186 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

Advancing to step 6:
68 divided by 20 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 11993.0
If we subtract 60 from 68, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 11993.4
Subtract 80 from 80 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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11993.4
The remainder is 0 after subtracting 0 from 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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11993.4
If we take 0 away from 0, we end up 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.

After the division, we end up with 11993.4 and a remainder of 0.0.
