664373 divided by 3 
Let's see how many times 3 fits into 664373.

Advancing to step 1:
6 divided by 3 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

On to step 2:
If we divide 6 by 3, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 6 from 6 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Advancing to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Deduct 3 from 4 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Let's proceed to step 4:
13 divided by 3 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 2214.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Step 5:
3 goes into 17 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 22145.0
If we subtract 15 from 17, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

On to step 6:
If we divide 23 by 3, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 221457.0
Deduct 21 from 23 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.

Step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 221457.6
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.

Step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 221457.66
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.

After the division, we end up with 221457.66 and a remainder of 0.002.
