We divide 578660 by 3
Let's see how many times 3 fits into 578660.

Going ahead to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Let's proceed to step 2:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 0 after subtracting 27 from 27.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
If we subtract 6 from 8, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Going ahead to step 4:
26 divided by 3 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
If we subtract 24 from 26, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Going ahead to step 5:
When dividing 26 by 3, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 19288.0
The remainder is 2 after subtracting 24 from 26.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Moving on to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 192886.0
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.

On to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 192886.6
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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 192886.66
If we take 18 away from 20, 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.

The final result is 192886.66 with a remainder of 0.002.
