We look at the division of 590858 by 3 
We're looking to find how many times 3 goes into 590858.

Let's proceed to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 3 from 5.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

On to step 2:
29 divided by 3 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 27 away from 29, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 3:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtract 18 from 20 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Step 4:
If we divide 28 by 3, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1969.0
Subtract 27 from 28 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Step 5:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19695.0
Deduct 15 from 15 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Let's proceed to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 196952.0
Deduct 6 from 8 and we're left 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.

Let's proceed to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 196952.6
If we subtract 18 from 20, we 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.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 196952.66
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.

The final result is 196952.66 with a remainder of 0.002.
