402143 divided by 24 
Let's see how many times 24 fits into 402143.

Step 1:
4 divided by 24 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 24

Let's proceed to step 2:
When dividing 40 by 24, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 24 from 40 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 24

Going ahead to step 3:
24 goes into 162 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 144 away from 162, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 24

Going ahead to step 4:
When dividing 181 by 24, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we take 168 away from 181, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 24

Step 5:
24 can be fit into 134 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 1675.0
If we take 120 away from 134, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 24

On to step 6:
The number 24 fits into 143 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 16755.0
Subtract 120 from 143 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 24 is 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 16755.9
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
24 goes into 140 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 16755.95
If we take 120 away from 140, 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.

Advancing to step 9:
If we divide 200 by 24, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 16755.958
If we subtract 192 from 200, 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.

On to step 10:
80 divided by 24 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 16755.9583
If we take 72 away from 80, we end up 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.

Let's proceed 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: 16755.95833
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.

Our division results in 16755.95833 with a remaining 8e-06.
