515325 divided by 30 
We want to figure out the number of times 515325 can be divided by 30.

Let's proceed to step 1:
30 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 30

Moving on to step 2:
30 goes into 51 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 30 from 51 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 30

Let's proceed to step 3:
215 divided by 30 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 210 away from 215, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Going ahead to step 4:
30 goes into 53 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 30 from 53 leaves us with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 30

Let's proceed to step 5:
When dividing 232 by 30, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 1717.0
Subtracting 210 from 232 leaves us with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 30

Step 6:
225 divided by 30 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 17177.0
If we subtract 210 from 225, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 30, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17177.5
If we subtract 150 from 150, 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.

Let's proceed to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17177.5
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.

Going ahead to step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17177.5
If we subtract 0 from 0, 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.

In conclusion, the division gives 17177.5 with a balance of 0.0.
