453484 ÷ 24 
We're looking to find how many times 24 goes into 453484.

Moving on to step 1:
If we divide 4 by 24, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 24

Moving on to step 2:
45 divided by 24 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 24 from 45, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 24

Moving on to step 3:
The number 24 fits into 213 8 times, leaving a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 192 from 213 leaves us with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 24

Let's proceed to step 4:
214 divided by 24 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 192 from 214 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 24

Let's proceed to step 5:
If we divide 228 by 24, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 1889.0
Deduct 216 from 228 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 24

On to step 6:
24 can be fit into 124 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 18895.0
The remainder is 4 after subtracting 120 from 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 24, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 18895.1
If we subtract 24 from 40, 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 8:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 18895.16
Subtracting 144 from 160 leaves us 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.

On to step 9:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 18895.166
The remainder is 16 after subtracting 144 from 160.
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 outcome is 18895.166, with a leftover of 0.0016.
