776343 divided by 12 
Let's see how many times 12 fits into 776343.

Advancing to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 12

Let's proceed to step 2:
When dividing 77 by 12, we get 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 72 from 77 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 12

On to step 3:
If we divide 56 by 12, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 48 from 56 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Let's proceed to step 4:
83 divided by 12 is 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 646.0
The remainder is 11 after subtracting 72 from 83.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 12

Moving on to step 5:
114 divided by 12 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 6469.0
Subtract 108 from 114 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Advancing to step 6:
12 goes into 63 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 64695.0
Subtract 60 from 63 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 64695.2
Subtracting 24 from 30 leaves us 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.

Advancing to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 64695.25
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.
The next digit of our result is 0. 
Result so far: 64695.25
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 10:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 64695.25
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.

Our division results in 64695.25 with a remaining 0.0.
