645353 divided by 24 
Let's see how many times 24 fits into 645353.

Let's proceed to step 1:
If we divide 6 by 24, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 24

Let's proceed to step 2:
64 divided by 24 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 48 from 64 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 24

On to step 3:
24 can be fit into 165 6 times, resulting in a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 144 from 165 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 24

On to step 4:
When dividing 213 by 24, we get 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
The remainder is 21 after subtracting 192 from 213.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 24

Step 5:
24 can be fit into 215 8 times, resulting in a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 2688.0
If we take 192 away from 215, we end up with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 24

Moving on to step 6:
24 goes into 233 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 26889.0
Subtracting 216 from 233 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
24 can be fit into 170 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 26889.7
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
24 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 26889.7
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
24 can be fit into 200 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 26889.708
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
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: 26889.7083
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 11:
If we divide 80 by 24, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 26889.70833
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.

The quotient of the division is 26889.70833, and the remainder is 8e-06.
