12417 ÷ 3 
We're looking to find how many times 3 goes into 12417.

Moving on to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Moving on to step 2:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 12 from 12 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Let's proceed to step 3:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 3 from 4 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Moving on to step 4:
3 goes into 11 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 413.0
Subtracting 9 from 11 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Going ahead to step 5:
27 divided by 3 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 4139.0
If we subtract 27 from 27, we get 0.
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 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4139.0
Deduct 0 from 0 and we're left 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 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4139.0
Subtract 0 from 0 to get 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 4139.0, with a leftover of 0.0.
