We're dividing 40240529 by 12 
We want to divide 40240529 by 12.

Moving on to step 1:
12 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 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.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 36 from 40 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 3:
12 goes into 42 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 36 away from 42, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

On to step 4:
When dividing 64 by 12, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 335.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 12

Advancing to step 5:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3353.0
If we subtract 36 from 40, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 12

On to step 6:
The number 12 fits into 45 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 33533.0
If we subtract 36 from 45, we get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 12

Step 7:
12 goes into 92 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 335337.0
If we take 84 away from 92, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

Step 8:
The number 12 fits into 89 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 3353377.0
If we subtract 84 from 89, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
12 goes into 50 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3353377.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 3353377.41
Subtracting 12 from 20 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.

Step 11:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3353377.416
Subtract 72 from 80 to 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.

Going ahead to step 12:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3353377.4166
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.

In conclusion, the division gives 3353377.4166 with a balance of 8e-05.
