We look at the division of 578487 by 3 
Our goal is to divide 578487 by 3.

Let's proceed to step 1:
5 divided by 3 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Let's proceed to step 2:
3 goes into 27 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
If we take 27 away from 27, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Moving on to step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 192.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

On to step 4:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1928.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Advancing to step 5:
When dividing 8 by 3, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 19282.0
Deduct 6 from 8 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Let's proceed to step 6:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 192829.0
If we subtract 27 from 27, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 192829.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 192829.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 192829.0, with a leftover of 0.0.
