We're dividing 409235 by 12 
We're looking to find how many times 12 goes into 409235.

Let's proceed to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 12

Advancing 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
If we take 36 away from 40, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Step 3:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 48 from 49 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 12

On to step 4:
12 can be fit into 12 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 341.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Advancing to step 5:
12 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 3410.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 12

Going ahead to step 6:
12 goes into 35 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 34102.0
If we take 24 away from 35, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 34102.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 34102.91
If we take 12 away from 20, 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.

Advancing to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 34102.916
Deduct 72 from 80 and we're left 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.

Step 10:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 34102.9166
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.

In conclusion, the division gives 34102.9166 with a balance of 8e-05.
