We look at the division of 290870 by 24 
Let's see how many times 24 fits into 290870.

Step 1:
2 divided by 24 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 24

Step 2:
29 divided by 24 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 24 from 29 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 24

Step 3:
When dividing 50 by 24, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 2 after subtracting 48 from 50.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 24

Moving on to step 4:
The number 24 fits into 28 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 24 from 28 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 24

Advancing to step 5:
47 divided by 24 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1211.0
If we subtract 24 from 47, we get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 24

Moving on to step 6:
The number 24 fits into 230 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 12119.0
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 24 fits into 140 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 12119.5
Subtract 120 from 140 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 24, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 12119.58
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 24 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 12119.583
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 24 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 12119.5833
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 12119.5833, with a leftover of 8e-05.
