Let's divide 687814 by 3
Our goal is to divide 687814 by 3.

Step 1:
3 goes into 6 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Advancing to step 2:
If we divide 8 by 3, we get 2 and 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.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Let's proceed to step 3:
3 can be fit into 27 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we take 27 away from 27, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Advancing to step 4:
3 goes into 8 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2292.0
If we take 6 away from 8, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Let's proceed to step 5:
21 divided by 3 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 22927.0
Subtracting 21 from 21 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

On to step 6:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 229271.0
Subtract 3 from 4 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 229271.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 229271.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 229271.33 and a remainder of 0.001.
