We look at the division of 286511 by 3 
We want to divide 286511 by 3.

Going ahead to step 1:
3 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Advancing to step 2:
3 goes into 28 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 27 from 28, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Advancing to step 3:
3 goes into 16 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 95.0
If we subtract 15 from 16, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Advancing to step 4:
When dividing 15 by 3, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 955.0
Deduct 15 from 15 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Advancing to step 5:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 9550.0
If we subtract 0 from 1, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

Advancing to step 6:
If we divide 11 by 3, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 95503.0
The remainder is 2 after subtracting 9 from 11.
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:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 95503.6
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.

Going ahead to step 8:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 95503.66
Deduct 18 from 20 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.

The final result is 95503.66 with a remainder of 0.002.
