Let's divide 40240132 by 12
Our goal is to divide 40240132 by 12.

On to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

Moving on to step 2:
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: 3.0
Deduct 36 from 40 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 12

Moving on to step 3:
12 can be fit into 42 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 36 away from 42, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 12

Advancing to step 4:
12 can be fit into 64 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
The remainder is 4 after subtracting 60 from 64.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

Step 5:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 3353.0
Deduct 36 from 40 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 12

Let's proceed to step 6:
12 can be fit into 41 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 33533.0
Subtracting 36 from 41 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 12

Step 7:
The number 12 fits into 53 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 335334.0
If we take 48 away from 53, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 12

Advancing to step 8:
52 divided by 12 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 3353344.0
Subtracting 48 from 52 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.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3353344.3
Subtract 36 from 40 to 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.

Let's proceed to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3353344.33
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.

The final result is 3353344.33 with a remainder of 0.004.
