We look at the division of 539599 by 20 
Our goal is to divide 539599 by 20.

Going ahead to step 1:
20 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 20

Moving on to step 2:
The number 20 fits into 53 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 53, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 20

On to step 3:
If we divide 139 by 20, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 120 away from 139, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

Going ahead to step 4:
When dividing 195 by 20, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 269.0
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

Let's proceed to step 5:
The number 20 fits into 159 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 2697.0
The remainder is 19 after subtracting 140 from 159.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 20

Moving on to step 6:
The number 20 fits into 199 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 26979.0
If we take 180 away from 199, we end up 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.

Advancing to step 7:
190 divided by 20 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 26979.9
Subtract 180 from 190 to 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.

Advancing to 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: 26979.95
Subtracting 100 from 100 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.

On to step 9:
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: 26979.95
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.

On 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: 26979.95
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.

The final result is 26979.95 with a remainder of 0.0.
