We divide 288489 by 20
We want to divide 288489 by 20.

Step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 20

Let's proceed to step 2:
When dividing 28 by 20, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 20 from 28 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Moving on to step 3:
20 can be fit into 88 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 80 away from 88, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

Moving on to step 4:
When dividing 84 by 20, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we take 80 away from 84, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Let's proceed to step 5:
20 can be fit into 48 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1442.0
If we take 40 away from 48, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 20

On to step 6:
The number 20 fits into 89 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 14424.0
If we take 80 away from 89, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 14424.4
If we take 80 away from 90, 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.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14424.45
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14424.45
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14424.45
Subtracting 0 from 0 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.

Our division results in 14424.45 with a remaining 0.0.
