We look at the division of 780302 by 15 
We want to figure out the number of times 780302 can be divided by 15.

On to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

On to step 2:
15 can be fit into 78 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 78, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 15

Advancing to step 3:
15 goes into 30 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 30 from 30 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 15

Step 4:
When dividing 3 by 15, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 520.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 15

Advancing to step 5:
30 divided by 15 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 5202.0
The remainder is 0 after subtracting 30 from 30.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 15

Moving on to step 6:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 52020.0
Subtract 0 from 2 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 52020.1
If we take 15 away from 20, 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.

Going ahead to step 8:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 52020.13
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.

Let's proceed to step 9:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 52020.133
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 52020.133 with a remainder of 0.0005.
