We divide 863638 by 24
We're looking to find how many times 24 goes into 863638.

Step 1:
8 divided by 24 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 24

Going ahead to step 2:
24 can be fit into 86 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 72 from 86 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 24

On to step 3:
24 goes into 143 5 times with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 120 away from 143, we end up with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 24

Let's proceed to step 4:
The number 24 fits into 236 9 times, leaving a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 359.0
Subtracting 216 from 236 leaves us with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 24

Going ahead to step 5:
If we divide 203 by 24, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 3598.0
Deduct 192 from 203 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 24

Advancing to step 6:
24 goes into 118 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 35984.0
Deduct 96 from 118 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 24 fits into 220 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 35984.9
If we subtract 216 from 220, 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.

Let's proceed to step 8:
40 divided by 24 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 35984.91
Deduct 24 from 40 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 24 fits into 160 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 35984.916
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 35984.9166
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 35984.9166 with a remainder of 0.00016.
