519866 ÷ 6 
We want to divide 519866 by 6.

Step 1:
6 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 6

Moving on to step 2:
6 can be fit into 51 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 48 from 51 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Going ahead to step 3:
6 can be fit into 39 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

On to step 4:
If we divide 38 by 6, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we take 36 away from 38, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 6

Going ahead to step 5:
6 goes into 26 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 8664.0
The remainder is 2 after subtracting 24 from 26.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 6

Advancing to step 6:
When dividing 26 by 6, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 86644.0
Deduct 24 from 26 and we're left 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.

Let's proceed to step 7:
20 divided by 6 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 86644.3
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.

Advancing to step 8:
20 divided by 6 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 86644.33
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.

The final outcome is 86644.33, with a leftover of 0.002.
