We look at the division of 505648 by 3 
We want to divide 505648 by 3.

Going ahead to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Step 2:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 18 from 20 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Advancing to step 3:
25 divided by 3 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Subtract 24 from 25 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Step 4:
3 goes into 16 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1685.0
The remainder is 1 after subtracting 15 from 16.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 5:
14 divided by 3 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 16854.0
Subtract 12 from 14 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Let's proceed to step 6:
28 divided by 3 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 168549.0
Deduct 27 from 28 and we're left 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.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 168549.3
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.

Step 8:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 168549.33
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 168549.33, and the remainder is 0.001.
