We look at the division of 436040 by 15 
Let's see how many times 15 fits into 436040.

Let's proceed to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 15

Step 2:
43 divided by 15 is 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 43, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 15

On to step 3:
136 divided by 15 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 135 from 136 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 15

Let's proceed to step 4:
If we divide 10 by 15, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 290.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 15

Going ahead to step 5:
104 divided by 15 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 2906.0
Subtracting 90 from 104 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 15

Step 6:
140 divided by 15 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 29069.0
The remainder is 5 after subtracting 135 from 140.
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 7:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 29069.3
Subtract 45 from 50 to 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.

Moving on to step 8:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 29069.33
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 29069.33, with a leftover of 0.005.
