426778 divided by 12 
We want to divide 426778 by 12.

Advancing to step 1:
12 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 12

Let's proceed to step 2:
When dividing 42 by 12, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 36 from 42 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Moving on to step 3:
If we divide 66 by 12, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 6 after subtracting 60 from 66.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 12

Advancing to step 4:
12 can be fit into 67 5 times, resulting in a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Subtract 60 from 67 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 12

Let's proceed to step 5:
77 divided by 12 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 3556.0
Subtracting 72 from 77 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 12

Moving on to step 6:
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: 35564.0
If we subtract 48 from 58, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 35564.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 35564.83
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 35564.833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 35564.833 and a remainder of 0.0004.
