515000 divided by 3 
We're looking to find how many times 3 goes into 515000.

Advancing to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Advancing to step 2:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 21 from 21, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Step 3:
5 divided by 3 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
If we subtract 3 from 5, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Let's proceed to step 4:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1716.0
If we take 18 away from 20, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

On to step 5:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 17166.0
If we subtract 18 from 20, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Step 6:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 171666.0
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 171666.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 171666.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 171666.66 with a remaining 0.002.
