421472 divided by 24 
We're looking to find how many times 24 goes into 421472.

Going ahead to step 1:
24 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 24

On to step 2:
24 can be fit into 42 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 24 away from 42, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 24

Moving on to step 3:
The number 24 fits into 181 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 168 from 181, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 24

Let's proceed to step 4:
24 goes into 134 5 times with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
Subtracting 120 from 134 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 24

Moving on to step 5:
When dividing 147 by 24, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 1756.0
If we take 144 away from 147, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 24

On to step 6:
32 divided by 24 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 17561.0
Subtract 24 from 32 to 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.

Step 7:
If we divide 80 by 24, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 17561.3
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.

Going ahead to step 8:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 17561.33
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.

Our division results in 17561.33 with a remaining 0.008.
