394358 divided by 12 
We want to figure out the number of times 394358 can be divided by 12.

On to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Advancing to step 2:
12 can be fit into 39 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 36 from 39 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

Step 3:
34 divided by 12 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 10 after subtracting 24 from 34.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Going ahead to step 4:
The number 12 fits into 103 8 times, leaving a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 328.0
Subtracting 96 from 103 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 12

Let's proceed to step 5:
If we divide 75 by 12, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 3286.0
Subtracting 72 from 75 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

On to step 6:
38 divided by 12 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 32863.0
Subtracting 36 from 38 leaves us with 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:
If we divide 20 by 12, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 32863.1
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.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 32863.16
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.

Let's proceed to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 32863.166
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.

The final result is 32863.166 with a remainder of 0.0008.
