720559 ÷ 20 
Let's see how many times 20 fits into 720559.

Moving on to step 1:
7 divided by 20 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

On to step 2:
When dividing 72 by 20, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 12 after subtracting 60 from 72.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 20

Going ahead to step 3:
If we divide 120 by 20, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 0 after subtracting 120 from 120.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 20

On to step 4:
If we divide 5 by 20, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 20

Step 5:
If we divide 55 by 20, we get 2 and a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 3602.0
If we take 40 away from 55, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 20

Advancing to step 6:
If we divide 159 by 20, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 36027.0
The remainder is 19 after subtracting 140 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 36027.9
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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 36027.95
Subtract 100 from 100 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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36027.95
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 36027.95
Deduct 0 from 0 and we're left 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 final outcome is 36027.95, with a leftover of 0.0.
