416448 ÷ 12 
We're looking to find how many times 12 goes into 416448.

On to step 1:
The number 12 fits into 4 0 times, leaving 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.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 12

Let's proceed to step 2:
12 goes into 41 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
If we take 36 away from 41, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 12

On to step 3:
56 divided by 12 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 48 from 56 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

Let's proceed to step 4:
84 divided by 12 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 347.0
If we take 84 away from 84, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 12

Advancing to step 5:
When dividing 4 by 12, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 3470.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 12

Moving on to step 6:
The number 12 fits into 48 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 34704.0
The remainder is 0 after subtracting 48 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34704.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34704.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 34704.0, with a leftover of 0.0.
