We look at the division of 508575 by 3 
Let's see how many times 3 fits into 508575.

Moving on to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Going ahead to step 2:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 18 from 20, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Advancing to step 3:
28 divided by 3 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtracting 27 from 28 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Going ahead to step 4:
When dividing 15 by 3, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1695.0
Subtract 15 from 15 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Moving on to step 5:
When dividing 7 by 3, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 16952.0
If we take 6 away from 7, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Moving on to step 6:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 169525.0
Deduct 15 from 15 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.

Advancing to step 7:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 169525.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 169525.0
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 169525.0, with a leftover of 0.0.
