We divide 408914 by 12
We're looking to find how many times 12 goes into 408914.

Moving on to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 12

On to step 2:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 36 away from 40, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 12

Let's proceed to step 3:
The number 12 fits into 48 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 48 from 48, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Let's proceed to step 4:
12 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 340.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

Advancing to step 5:
12 can be fit into 91 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 3407.0
Deduct 84 from 91 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 12

Step 6:
If we divide 74 by 12, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 34076.0
Subtracting 72 from 74 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.

Let's proceed to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 34076.1
Subtracting 12 from 20 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.

Let's proceed to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 34076.16
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.

Advancing to step 9:
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: 34076.166
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.

The final outcome is 34076.166, with a leftover of 0.0008.
