Let's divide 309642 by 24
We want to figure out the number of times 309642 can be divided by 24.

Let's proceed 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
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 24

On to step 2:
If we divide 30 by 24, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 24 away from 30, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 24

Going ahead to step 3:
24 can be fit into 69 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 48 from 69 leaves us with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 24

Let's proceed to step 4:
If we divide 216 by 24, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 129.0
Deduct 216 from 216 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 24

Let's proceed to step 5:
4 divided by 24 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 1290.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 24

Step 6:
24 can be fit into 42 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 12901.0
Subtract 24 from 42 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 24 fits into 180 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 12901.7
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 24, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12901.75
If we take 120 away from 120, we end up with 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 9:
24 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12901.75
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 10:
When dividing 0 by 24, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12901.75
Subtracting 0 from 0 leaves us with 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 12901.75, with a leftover of 0.0.
