780810 ÷ 12 
Our goal is to divide 780810 by 12.

Let's proceed to step 1:
7 divided by 12 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Moving on to step 2:
12 goes into 78 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 72 away from 78, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Let's proceed to step 3:
12 goes into 60 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 60 from 60 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 12

Going ahead to step 4:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 650.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

Moving on to step 5:
12 goes into 81 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 6506.0
The remainder is 9 after subtracting 72 from 81.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 12

Going ahead to step 6:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 65067.0
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65067.5
Subtracting 60 from 60 leaves us 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:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65067.5
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.

Moving on to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 65067.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 65067.5 with a balance of 0.0.
