507489 ÷ 3 
Our goal is to divide 507489 by 3.

On to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Going ahead to step 2:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 18 from 20 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

On to step 3:
3 goes into 27 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 169.0
Subtract 27 from 27 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

On to step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.0
Subtracting 3 from 4 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16916.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Step 6:
9 divided by 3 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 169163.0
Deduct 9 from 9 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.

Let's proceed to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 169163.0
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 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 169163.0
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.

Our division results in 169163.0 with a remaining 0.0.
