Let's divide 510525 by 15
We want to divide 510525 by 15.

Going ahead to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 15

Step 2:
If we divide 51 by 15, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 45 from 51 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Going ahead to step 3:
If we divide 60 by 15, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 60 from 60 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Moving on to step 4:
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: 340.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Moving on to step 5:
15 can be fit into 52 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3403.0
Deduct 45 from 52 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 15

Step 6:
15 can be fit into 75 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 34035.0
Deduct 75 from 75 and we're left 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.

On to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34035.0
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.

Going ahead to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34035.0
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 34035.0, with a leftover of 0.0.
