We're dividing 409352 by 12 
We want to figure out the number of times 409352 can be divided by 12.

Let's proceed to step 1:
12 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Going ahead to step 2:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 4 after subtracting 36 from 40.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 12

On to step 3:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 48 from 49, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 12

Moving on to step 4:
When dividing 13 by 12, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 341.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

On to step 5:
When dividing 15 by 12, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 3411.0
Deduct 12 from 15 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 12

Going ahead to step 6:
32 divided by 12 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 34112.0
If we take 24 away from 32, we end up 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.

Moving on to step 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 34112.6
Subtracting 72 from 80 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.

Advancing to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 34112.66
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.

The final result is 34112.66 with a remainder of 0.008.
