729790 ÷ 20 
Our goal is to divide 729790 by 20.

Going ahead to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

Going ahead to step 2:
20 goes into 72 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 72, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Going ahead to step 3:
20 can be fit into 129 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 120 from 129, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 20

On to step 4:
97 divided by 20 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 364.0
If we subtract 80 from 97, we get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 20

Advancing to step 5:
179 divided by 20 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 3648.0
Subtracting 160 from 179 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 20

Let's proceed to step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 36489.0
Deduct 180 from 190 and we're left 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 7:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 36489.5
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 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36489.5
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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36489.5
If we subtract 0 from 0, we 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 36489.5 with a remainder of 0.0.
