We look at the division of 490618 by 3 
Our goal is to divide 490618 by 3.

Advancing to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Let's proceed to step 2:
If we divide 19 by 3, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 18 from 19, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Advancing to step 3:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 163.0
Subtract 9 from 10 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

On to step 4:
16 divided by 3 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 1635.0
The remainder is 1 after subtracting 15 from 16.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

On to step 5:
11 divided by 3 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 16353.0
Subtracting 9 from 11 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Moving on to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 163539.0
If we subtract 27 from 28, we 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.

Moving on to step 7:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 163539.3
If we subtract 9 from 10, we 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.

Moving on to step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 163539.33
If we subtract 9 from 10, we 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.

The quotient of the division is 163539.33, and the remainder is 0.001.
