Let's divide 405181 by 12
We want to figure out the number of times 405181 can be divided by 12.

Step 1:
4 divided by 12 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Moving on to step 2:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 36 from 40, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Let's proceed to step 3:
12 goes into 45 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 36 from 45 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 12

Going ahead to step 4:
91 divided by 12 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 337.0
If we take 84 away from 91, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Step 5:
When dividing 78 by 12, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3376.0
If we take 72 away from 78, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 12

Step 6:
When dividing 61 by 12, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 33765.0
Subtracting 60 from 61 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 33765.0
Subtracting 0 from 10 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.

Going ahead to step 8:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 33765.08
Subtracting 96 from 100 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.

Going ahead to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33765.083
Deduct 36 from 40 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.

Let's proceed to step 10:
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: 33765.0833
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.

The final result is 33765.0833 with a remainder of 4e-05.
