We divide 510570 by 30
We want to divide 510570 by 30.

Advancing to step 1:
The number 30 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 30

On to step 2:
If we divide 51 by 30, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 51, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 30

Moving on to step 3:
If we divide 210 by 30, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 210 from 210, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 30

On to step 4:
When dividing 5 by 30, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 30

Let's proceed to step 5:
If we divide 57 by 30, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
Subtract 30 from 57 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 30

Let's proceed to step 6:
The number 30 fits into 270 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 17019.0
Subtract 270 from 270 to 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.

Going ahead to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17019.0
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:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17019.0
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.

The final outcome is 17019.0, with a leftover of 0.0.
