Let's divide 685664 by 3
We're looking to find how many times 3 goes into 685664.

Let's proceed to step 1:
6 divided by 3 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

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
Subtract 6 from 8 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Step 3:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 228.0
Subtract 24 from 25 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Moving on to step 4:
When dividing 16 by 3, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 2285.0
If we subtract 15 from 16, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Let's proceed to step 5:
16 divided by 3 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 22855.0
The remainder is 1 after subtracting 15 from 16.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Going ahead to step 6:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 228554.0
If we take 12 away from 14, 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 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 228554.6
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.

Advancing to step 8:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 228554.66
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.

Our division results in 228554.66 with a remaining 0.002.
