We look at the division of 419396 by 12 
We want to figure out the number of times 419396 can be divided by 12.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the 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:
If we divide 41 by 12, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 36 from 41 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Step 3:
59 divided by 12 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 48 from 59, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

Advancing to step 4:
The number 12 fits into 113 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 349.0
If we subtract 108 from 113, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Step 5:
59 divided by 12 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 3494.0
Subtract 48 from 59 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Moving on to step 6:
If we divide 116 by 12, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 34949.0
Subtracting 108 from 116 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 7:
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: 34949.6
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.

Step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 34949.66
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.

Our division results in 34949.66 with a remaining 0.008.
