We divide 521532 by 15
We're looking to find how many times 15 goes into 521532.

On to step 1:
5 divided by 15 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Moving on to step 2:
If we divide 52 by 15, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 45 from 52 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 15

Advancing to step 3:
The number 15 fits into 71 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 60 away from 71, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 15

On to step 4:
15 can be fit into 115 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 347.0
If we subtract 105 from 115, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 15

Advancing to step 5:
The number 15 fits into 103 6 times, leaving a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 3476.0
The remainder is 13 after subtracting 90 from 103.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 15

Moving on to step 6:
15 goes into 132 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 34768.0
If we subtract 120 from 132, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 34768.8
The remainder is 0 after subtracting 120 from 120.
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:
15 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: 34768.8
If we take 0 away from 0, we end up 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 9:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34768.8
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 34768.8, with a leftover of 0.0.
