We look at the division of 40451995 by 15 
Let's see how many times 15 fits into 40451995.

Going ahead to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

Advancing to step 2:
If we divide 40 by 15, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 30 from 40 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 15

Moving on to step 3:
The number 15 fits into 104 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 90 from 104 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 15

On to step 4:
The number 15 fits into 145 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 269.0
Subtract 135 from 145 to get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

Going ahead to step 5:
If we divide 101 by 15, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 2696.0
If we subtract 90 from 101, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 15

Going ahead to step 6:
If we divide 119 by 15, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 26967.0
If we subtract 105 from 119, we get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

On to step 7:
149 divided by 15 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 269679.0
The remainder is 14 after subtracting 135 from 149.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 15

Let's proceed to step 8:
15 goes into 145 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 2696799.0
Deduct 135 from 145 and we're left 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.

Step 9:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 2696799.6
Subtract 90 from 100 to get 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 10:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 2696799.66
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2696799.66 with a remaining 0.01.
