We're dividing 774945 by 12 
We're looking to find how many times 12 goes into 774945.

On to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 12

Advancing to step 2:
When dividing 77 by 12, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 72 away from 77, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 12

On to step 3:
54 divided by 12 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 48 away from 54, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 12

Step 4:
12 goes into 69 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 645.0
Subtracting 60 from 69 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 12

On to step 5:
12 goes into 94 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 6457.0
Subtract 84 from 94 to get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 12

Going ahead to step 6:
The number 12 fits into 105 8 times, leaving a remainder of 9.
The next digit of our result is 8. 
Result so far: 64578.0
The remainder is 9 after subtracting 96 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 64578.7
Subtract 84 from 90 to 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.

Moving on to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 64578.75
Subtract 60 from 60 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.

On to step 9:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64578.75
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.

Going ahead to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 64578.75
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.

The final outcome is 64578.75, with a leftover of 0.0.
