636242 ÷ 15 
Let's see how many times 15 fits into 636242.

Moving on to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 15

On to step 2:
15 goes into 63 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 3 after subtracting 60 from 63.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

On to step 3:
The number 15 fits into 36 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 30 from 36 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 15

On to step 4:
The number 15 fits into 62 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 424.0
The remainder is 2 after subtracting 60 from 62.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 15

On to step 5:
The number 15 fits into 24 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4241.0
If we take 15 away from 24, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 15

Let's proceed to step 6:
If we divide 92 by 15, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 42416.0
The remainder is 2 after subtracting 90 from 92.
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 7:
20 divided by 15 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 42416.1
Subtracting 15 from 20 leaves us 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.

Going ahead to step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 42416.13
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.

Let's proceed to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 42416.133
If we take 45 away from 50, we end up 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 result is 42416.133 with a remainder of 0.0005.
