We're dividing 453539 by 24 
Let's see how many times 24 fits into 453539.

On to step 1:
24 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 24

Step 2:
45 divided by 24 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 24 from 45, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 24

Advancing to step 3:
24 can be fit into 213 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 192 from 213 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 24

On to step 4:
24 goes into 215 8 times with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Subtract 192 from 215 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 24

On to step 5:
When dividing 233 by 24, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 1889.0
Subtract 216 from 233 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 24

Step 6:
When dividing 179 by 24, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 18897.0
If we take 168 away from 179, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 24 fits into 110 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 18897.4
Subtract 96 from 110 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.

Moving on to step 8:
When dividing 140 by 24, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 18897.45
Subtracting 120 from 140 leaves us 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:
24 can be fit into 200 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 18897.458
Subtract 192 from 200 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.

Let's proceed to step 10:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 18897.4583
Subtract 72 from 80 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.

Going ahead to step 11:
When dividing 80 by 24, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 18897.45833
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.

After the division, we end up with 18897.45833 and a remainder of 8e-06.
