We're dividing 511292 by 3 
Our goal is to divide 511292 by 3.

Advancing to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Moving on to step 2:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 0 after subtracting 21 from 21.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

On to step 3:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Step 4:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1704.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 5:
3 goes into 9 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 17043.0
If we take 9 away from 9, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

On to step 6:
2 divided by 3 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 170430.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 170430.6
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.

On to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 170430.66
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.

The final outcome is 170430.66, with a leftover of 0.002.
