We look at the division of 305513 by 24 
Let's see how many times 24 fits into 305513.

Going ahead to step 1:
3 divided by 24 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 24

Let's proceed to step 2:
24 goes into 30 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 24 away from 30, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 24

Step 3:
65 divided by 24 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 48 from 65 and we're left with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 24

On to step 4:
175 divided by 24 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 7 after subtracting 168 from 175.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 24

Going ahead to step 5:
24 can be fit into 71 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
If we take 48 away from 71, we end up with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 24

Going ahead to step 6:
When dividing 233 by 24, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 12729.0
Subtract 216 from 233 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 24 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 12729.7
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 24, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12729.7
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 24, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 12729.708
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.

Step 10:
If we divide 80 by 24, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 12729.7083
Deduct 72 from 80 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.

Advancing to step 11:
24 goes into 80 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 12729.70833
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.

The final result is 12729.70833 with a remainder of 8e-06.
