778745 divided by 12 
Let's see how many times 12 fits into 778745.

Let's proceed to step 1:
7 divided by 12 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

Moving on to step 2:
77 divided by 12 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 77, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Going ahead to step 3:
When dividing 58 by 12, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 48 from 58 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 12

Going ahead to step 4:
12 can be fit into 107 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 648.0
Subtracting 96 from 107 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

On to step 5:
When dividing 114 by 12, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 6489.0
Subtracting 108 from 114 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 12

Step 6:
The number 12 fits into 65 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 64895.0
The remainder is 5 after subtracting 60 from 65.
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:
If we divide 50 by 12, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 64895.4
If we subtract 48 from 50, we 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 8:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 64895.41
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 64895.416
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 64895.4166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 64895.4166, with a leftover of 8e-05.
