585806 divided by 3 
Our goal is to divide 585806 by 3.

On to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Going ahead to step 2:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 27 from 28 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Advancing to step 3:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtracting 15 from 15 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Step 4:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1952.0
Deduct 6 from 8 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Going ahead to step 5:
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: 19526.0
If we subtract 18 from 20, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Advancing to step 6:
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: 195268.0
Subtract 24 from 26 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.

Step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 195268.6
Subtracting 18 from 20 leaves us 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.

On to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 195268.66
Subtracting 18 from 20 leaves us 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.

After the division, we end up with 195268.66 and a remainder of 0.002.
