648671 ÷ 3 
Let's see how many times 3 fits into 648671.

Let's proceed to step 1:
3 goes into 6 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Step 2:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 3 from 4 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Let's proceed to step 3:
3 goes into 18 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 18 from 18, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

On to step 4:
When dividing 6 by 3, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2162.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Advancing to step 5:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 21622.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Let's proceed to step 6:
3 goes into 11 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 216223.0
Subtract 9 from 11 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 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 216223.6
Subtracting 18 from 20 leaves us 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.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 216223.66
The remainder is 2 after subtracting 18 from 20.
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 216223.66 and a remainder of 0.002.
