We look at the division of 508529 by 15 
We want to figure out the number of times 508529 can be divided by 15.

Step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

Going ahead to step 2:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 45 from 50 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Step 3:
15 can be fit into 58 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtract 45 from 58 to get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 15

Advancing to step 4:
15 can be fit into 135 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 339.0
The remainder is 0 after subtracting 135 from 135.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 15

Let's proceed to step 5:
If we divide 2 by 15, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 3390.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 15

Advancing to step 6:
If we divide 29 by 15, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 33901.0
If we take 15 away from 29, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 15 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 33901.9
If we take 135 away from 140, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 33901.93
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 33901.933
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 33901.933 and a remainder of 0.0005.
