We're dividing 516019 by 3 
Let's see how many times 3 fits into 516019.

Advancing to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Advancing to step 2:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 0 after subtracting 21 from 21.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Advancing to step 3:
3 goes into 6 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtract 6 from 6 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Going ahead to step 4:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
Subtract 0 from 0 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Advancing to step 5:
3 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 17200.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 3

Moving on to step 6:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 172006.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 172006.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 172006.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 172006.33 with a remaining 0.001.
