We divide 780845 by 15
We're looking to find how many times 15 goes into 780845.

Step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Advancing to step 2:
78 divided by 15 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 75 from 78 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

On to step 3:
15 goes into 30 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 30 from 30 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Going ahead to step 4:
If we divide 8 by 15, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 520.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 15

Advancing to step 5:
84 divided by 15 is 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5205.0
Subtracting 75 from 84 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 15

Moving on to step 6:
15 goes into 95 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 52056.0
Subtracting 90 from 95 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.

Moving on to step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 52056.3
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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 52056.33
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 quotient of the division is 52056.33, and the remainder is 0.005.
