411643 divided by 12 
We want to figure out the number of times 411643 can be divided by 12.

On to step 1:
4 divided by 12 is 0 with 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.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 12

Going ahead 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
Subtract 36 from 41 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Moving on to step 3:
When dividing 51 by 12, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 48 from 51 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 12

On to step 4:
12 can be fit into 36 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 343.0
If we subtract 36 from 36, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 12

Let's proceed to step 5:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 3430.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

On to step 6:
If we divide 43 by 12, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 34303.0
Subtracting 36 from 43 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 34303.5
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 34303.58
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 34303.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 34303.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 34303.5833 and a remainder of 4e-05.
