686235 ÷ 3 
Our goal is to divide 686235 by 3.

Advancing to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

On to step 2:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Advancing to step 3:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 228.0
If we take 24 away from 26, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Advancing to step 4:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2287.0
The remainder is 1 after subtracting 21 from 22.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Advancing to step 5:
If we divide 13 by 3, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 22874.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Let's proceed to step 6:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 228745.0
Deduct 15 from 15 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.

Moving on to 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: 228745.0
Subtracting 0 from 0 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 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: 228745.0
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.

The final outcome is 228745.0, with a leftover of 0.0.
