We're dividing 242315 by 8 
We're looking to find how many times 8 goes into 242315.

Step 1:
2 divided by 8 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

Advancing to step 2:
24 divided by 8 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 24 from 24 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 8

On to step 3:
8 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 8

Moving on to step 4:
23 divided by 8 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
Subtract 16 from 23 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 8

Step 5:
71 divided by 8 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 3028.0
Deduct 64 from 71 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 8

Let's proceed to step 6:
If we divide 75 by 8, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 30289.0
If we take 72 away from 75, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 30289.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
8 goes into 60 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 30289.37
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 30289.375
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30289.375
The remainder is 0 after subtracting 0 from 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 11:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30289.375
The remainder is 0 after subtracting 0 from 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 final outcome is 30289.375, with a leftover of 0.0.
