We're dividing 778308 by 12 
Our goal is to divide 778308 by 12.

Going ahead to step 1:
7 divided by 12 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 12

Advancing to step 2:
The number 12 fits into 77 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 72 from 77 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 12

Step 3:
12 can be fit into 58 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
The remainder is 10 after subtracting 48 from 58.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

On to step 4:
When dividing 103 by 12, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 648.0
The remainder is 7 after subtracting 96 from 103.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 12

Step 5:
12 goes into 70 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6485.0
If we take 60 away from 70, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 12

Moving on to step 6:
12 goes into 108 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 64859.0
If we take 108 away from 108, 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.

Let's proceed to step 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 64859.0
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.

Moving on to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64859.0
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.

The final outcome is 64859.0, with a leftover of 0.0.
