Let's divide 720573 by 15
We want to divide 720573 by 15.

Going ahead to step 1:
15 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Going ahead to step 2:
15 can be fit into 72 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 12 after subtracting 60 from 72.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

On to step 3:
If we divide 120 by 15, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 120 away from 120, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 15

Going ahead to step 4:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Step 5:
15 can be fit into 57 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 4803.0
Subtract 45 from 57 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 15

On to step 6:
When dividing 123 by 15, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 48038.0
Subtract 120 from 123 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 can be fit into 30 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 48038.2
If we take 30 away from 30, 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.

Step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48038.2
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.

Going ahead to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 48038.2
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 quotient of the division is 48038.2, and the remainder is 0.0.
