We're dividing 242430 by 675 
We want to figure out the number of times 242430 can be divided by 675.

Step 1:
If we divide 2 by 675, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 675

Going ahead to step 2:
675 goes into 24 0 times with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 675

Step 3:
The number 675 fits into 242 0 times, leaving a remainder of 242.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 242 and we're left with 242.
Take the next digit (4) from the dividend and append it to 242, then repeat: 2424 / 675

Going ahead to step 4:
675 goes into 2424 3 times with a remainder of 399.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2025 away from 2424, we end up with 399.
Bring next digit (3) of the dividend behind the 399 and repeat the process: 3993 / 675

Step 5:
3993 divided by 675 is 5 with a remainder of 618.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 3375 from 3993, we get 618.
Fetch the next digit (0) from the dividend, attach it to 618 and continue: 6180 / 675

On to step 6:
If we divide 6180 by 675, we get 9 and a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 359.0
If we take 6075 away from 6180, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 7:
675 goes into 1050 1 times with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 359.1
Subtracting 675 from 1050 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 8:
When dividing 3750 by 675, we get 5 with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 359.15
Subtract 3375 from 3750 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 9:
675 can be fit into 3750 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 359.155
If we take 3375 away from 3750, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final outcome is 359.155, with a leftover of 0.0375.
