509136 ÷ 3 
We want to divide 509136 by 3.

Going ahead to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Advancing to step 2:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 18 away from 20, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Step 3:
29 divided by 3 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 169.0
If we subtract 27 from 29, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 4:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1697.0
Deduct 21 from 21 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

On to step 5:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 16971.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Going ahead to step 6:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 169712.0
Subtracting 6 from 6 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.

Step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 169712.0
Deduct 0 from 0 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.

On to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 169712.0
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.

Our division results in 169712.0 with a remaining 0.0.
