Let's divide 426080 by 12
We want to divide 426080 by 12.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Advancing to step 2:
If we divide 42 by 12, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 36 away from 42, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 12

Going ahead to step 3:
When dividing 66 by 12, we get 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 60 from 66 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Let's proceed to step 4:
If we divide 60 by 12, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 60 from 60 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 12

Advancing to step 5:
12 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 3550.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Moving on to step 6:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 35506.0
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.

Going ahead to step 7:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 35506.6
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.

On to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 35506.66
Subtracting 72 from 80 leaves us 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 result is 35506.66 with a remainder of 0.008.
