686570 divided by 3 
We want to divide 686570 by 3.

Going ahead to step 1:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Moving on to step 2:
8 divided by 3 is 2 with 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.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Let's proceed to step 3:
26 divided by 3 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Deduct 24 from 26 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Let's proceed to step 4:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 2288.0
If we subtract 24 from 25, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

On to step 5:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 22885.0
If we subtract 15 from 17, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Let's proceed to step 6:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 228856.0
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.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 228856.6
If we take 18 away from 20, we end up 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.

Step 8:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 228856.66
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.

After the division, we end up with 228856.66 and a remainder of 0.002.
