520180 ÷ 15 
Let's see how many times 15 fits into 520180.

Going ahead to step 1:
The number 15 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 subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 15

Advancing to step 2:
The number 15 fits into 52 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 45 from 52, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 15

Going ahead to step 3:
15 goes into 70 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 60 from 70 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

Step 4:
The number 15 fits into 101 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 346.0
Subtracting 90 from 101 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 15

Moving on to step 5:
The number 15 fits into 118 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3467.0
The remainder is 13 after subtracting 105 from 118.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 15

On to step 6:
If we divide 130 by 15, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 34678.0
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 34678.6
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 34678.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 34678.66, with a leftover of 0.01.
