Let's divide 434930 by 12
Our goal is to divide 434930 by 12.

Moving on to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Advancing to step 2:
12 goes into 43 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 36 from 43 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Going ahead to step 3:
If we divide 74 by 12, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 72 from 74 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

On to step 4:
29 divided by 12 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
The remainder is 5 after subtracting 24 from 29.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Moving on to step 5:
12 can be fit into 53 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 3624.0
Subtracting 48 from 53 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 12

Advancing to step 6:
If we divide 50 by 12, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 36244.0
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 36244.1
If we take 12 away from 20, 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:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 36244.16
If we subtract 72 from 80, 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.

Let's proceed to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 36244.166
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.

The final result is 36244.166 with a remainder of 0.0008.
