274242 ÷ 15 
We're looking to find how many times 15 goes into 274242.

Step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 15

Step 2:
When dividing 27 by 15, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 15 from 27, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 15

Moving on to step 3:
124 divided by 15 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 120 from 124 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

On to step 4:
The number 15 fits into 42 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 182.0
Subtract 30 from 42 to get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 15

Moving on to step 5:
15 can be fit into 124 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1828.0
Subtracting 120 from 124 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 15

Let's proceed to step 6:
42 divided by 15 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 18282.0
Subtract 30 from 42 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
15 goes into 120 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18282.8
Subtracting 120 from 120 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18282.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18282.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 18282.8, and the remainder is 0.0.
