780474 ÷ 12 
We want to divide 780474 by 12.

Let's proceed to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Let's proceed to step 2:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 72 from 78 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

Step 3:
12 goes into 60 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 60 from 60, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 12

Moving on to step 4:
When dividing 4 by 12, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 12

Advancing to step 5:
The number 12 fits into 47 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6503.0
If we take 36 away from 47, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Going ahead to step 6:
12 can be fit into 114 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 65039.0
If we take 108 away from 114, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 65039.5
If we take 60 away from 60, 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.

Advancing to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 65039.5
If we subtract 0 from 0, we 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.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 65039.5
If we subtract 0 from 0, we 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.

The final result is 65039.5 with a remainder of 0.0.
