Let's divide 430556 by 12
We're looking to find how many times 12 goes into 430556.

On to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

On to step 2:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 36 from 43 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 12

Let's proceed to step 3:
The number 12 fits into 70 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 60 away from 70, we end up with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 12

Let's proceed to step 4:
105 divided by 12 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 358.0
Subtracting 96 from 105 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 12

Going ahead to step 5:
12 can be fit into 95 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 3587.0
If we subtract 84 from 95, we get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Going ahead to step 6:
12 can be fit into 116 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 35879.0
If we subtract 108 from 116, 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.

Moving on to step 7:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 35879.6
Subtract 72 from 80 to 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.

Let's proceed to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 35879.66
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 35879.66 with a remaining 0.008.
