Let's divide 573963 by 3
Our goal is to divide 573963 by 3.

Step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 3 from 5 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Going ahead to step 2:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 27 away from 27, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 3:
When dividing 3 by 3, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we take 3 away from 3, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Going ahead to step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1913.0
If we subtract 9 from 9, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Step 5:
3 goes into 6 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 19132.0
If we subtract 6 from 6, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Let's proceed to step 6:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 191321.0
The remainder is 0 after subtracting 3 from 3.
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 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 191321.0
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.

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 191321.0
If we take 0 away from 0, 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.

The quotient of the division is 191321.0, and the remainder is 0.0.
