We look at the division of 649503 by 3 
We want to divide 649503 by 3.

Advancing 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
If we subtract 6 from 6, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Step 2:
3 goes into 4 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 3 from 4 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Moving on to step 3:
3 goes into 19 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
If we take 18 away from 19, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Going ahead to step 4:
3 goes into 15 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2165.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Moving on to step 5:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21650.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Let's proceed to step 6:
When dividing 3 by 3, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 216501.0
If we take 3 away from 3, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 216501.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 216501.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 216501.0 and a remainder of 0.0.
