We divide 288789 by 20
We want to divide 288789 by 20.

Let's proceed 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
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

Step 2:
28 divided by 20 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 20 from 28.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 20

Let's proceed to step 3:
The number 20 fits into 88 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 80 from 88 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 20

Advancing to step 4:
20 goes into 87 4 times with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 7 after subtracting 80 from 87.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Going ahead to step 5:
If we divide 78 by 20, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 1443.0
Subtracting 60 from 78 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 20

Step 6:
The number 20 fits into 189 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 14439.0
Subtracting 180 from 189 leaves us 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.

Moving on to step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 14439.4
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.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14439.45
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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14439.45
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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14439.45
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.

The final outcome is 14439.45, with a leftover of 0.0.
