Let's divide 491666 by 3
We want to divide 491666 by 3.

Advancing to step 1:
4 divided by 3 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

On to step 2:
19 divided by 3 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Going ahead to step 3:
When dividing 11 by 3, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 163.0
The remainder is 2 after subtracting 9 from 11.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Let's proceed to step 4:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1638.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

On to step 5:
If we divide 26 by 3, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 16388.0
If we take 24 away from 26, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Let's proceed to step 6:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 163888.0
If we take 24 away from 26, 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.

Moving on to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 163888.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 163888.66
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.

After the division, we end up with 163888.66 and a remainder of 0.002.
