We're dividing 503472 by 3 
Our goal is to divide 503472 by 3.

Let's proceed to step 1:
3 goes into 5 1 times with 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 (0) from the dividend, attach it to 2 and continue: 20 / 3

Let's proceed to step 2:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 18 from 20 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Advancing to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 21 from 23, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Let's proceed to step 4:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 1678.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Step 5:
7 divided by 3 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 16782.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Advancing to step 6:
12 divided by 3 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 167824.0
Subtracting 12 from 12 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 7:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 167824.0
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.

Let's proceed to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 167824.0
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.

In conclusion, the division gives 167824.0 with a balance of 0.0.
