Let's divide 283959 by 20
We want to divide 283959 by 20.

Going ahead 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
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 20

Let's proceed to step 2:
When dividing 28 by 20, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 28 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 20

Let's proceed to step 3:
83 divided by 20 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 3 after subtracting 80 from 83.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Let's proceed to step 4:
20 can be fit into 39 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 141.0
The remainder is 19 after subtracting 20 from 39.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 20

Going ahead to step 5:
20 goes into 195 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1419.0
Subtracting 180 from 195 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 20

On to step 6:
20 goes into 159 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 14197.0
Deduct 140 from 159 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.

Moving on to step 7:
If we divide 190 by 20, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 14197.9
If we subtract 180 from 190, we get 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.
The next digit of our result is 5. 
Result so far: 14197.95
If we take 100 away from 100, 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.

On to step 9:
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: 14197.95
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.

Advancing to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14197.95
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.

After the division, we end up with 14197.95 and a remainder of 0.0.
