288339 ÷ 20 
We want to divide 288339 by 20.

Going ahead to step 1:
2 divided by 20 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 20

Moving on to step 2:
The number 20 fits into 28 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 28, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 20

Advancing to step 3:
The number 20 fits into 88 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 80 away from 88, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

Let's proceed to step 4:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 80 from 83, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 20

Moving on to step 5:
20 can be fit into 33 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 1441.0
Subtract 20 from 33 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 20

On to step 6:
20 can be fit into 139 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 14416.0
Deduct 120 from 139 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 14416.9
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14416.95
The remainder is 0 after subtracting 100 from 100.
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 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14416.95
Subtract 0 from 0 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.

Advancing to step 10:
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: 14416.95
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.

The quotient of the division is 14416.95, and the remainder is 0.0.
