513042 ÷ 15 
We want to divide 513042 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
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 15

Going ahead to step 2:
If we divide 51 by 15, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 45 from 51, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 15

On to step 3:
If we divide 63 by 15, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 3 after subtracting 60 from 63.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

Step 4:
15 goes into 30 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 30 from 30 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 15

On to step 5:
When dividing 4 by 15, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 3420.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 15

Going ahead to step 6:
15 can be fit into 42 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 34202.0
If we subtract 30 from 42, 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.

Step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 34202.8
If we take 120 away from 120, 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.

Going ahead to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34202.8
Deduct 0 from 0 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.

Advancing to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34202.8
Deduct 0 from 0 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.

The quotient of the division is 34202.8, and the remainder is 0.0.
