664495 ÷ 3 
We want to divide 664495 by 3.

On to step 1:
The number 3 fits into 6 2 times, leaving 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.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Advancing to step 2:
The number 3 fits into 6 2 times, leaving 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.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Advancing to step 3:
4 divided by 3 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 221.0
Subtracting 3 from 4 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Going ahead to step 4:
If we divide 14 by 3, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2214.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Moving on to step 5:
If we divide 29 by 3, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 22149.0
The remainder is 2 after subtracting 27 from 29.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Moving on to step 6:
If we divide 25 by 3, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 221498.0
Subtract 24 from 25 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:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 221498.3
If we take 9 away from 10, we end up 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.

Going ahead to step 8:
10 divided by 3 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 221498.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 221498.33, and the remainder is 0.001.
