729515 ÷ 20 
Our goal is to divide 729515 by 20.

Let's proceed to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Advancing to step 2:
20 goes into 72 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 20

Advancing to step 3:
The number 20 fits into 129 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 120 from 129 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 20

Let's proceed to step 4:
20 can be fit into 95 4 times, resulting in a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 364.0
The remainder is 15 after subtracting 80 from 95.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 20

Advancing to step 5:
The number 20 fits into 151 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 3647.0
Subtract 140 from 151 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 20

Advancing to step 6:
If we divide 115 by 20, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 36475.0
The remainder is 15 after subtracting 100 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 36475.7
Subtract 140 from 150 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.

Step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 36475.75
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.

Let's proceed to step 9:
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: 36475.75
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 36475.75
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 36475.75, with a leftover of 0.0.
