We look at the division of 520536 by 3 
We're looking to find how many times 3 goes into 520536.

Advancing to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Moving on to step 2:
22 divided by 3 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 21 from 22 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Moving on to step 3:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Deduct 9 from 10 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Moving on to step 4:
When dividing 15 by 3, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1735.0
Subtracting 15 from 15 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Step 5:
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: 17351.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

On to step 6:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 173512.0
Subtract 6 from 6 to 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.

On to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 173512.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 173512.0
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.

In conclusion, the division gives 173512.0 with a balance of 0.0.
