645407 divided by 24 
We want to figure out the number of times 645407 can be divided by 24.

Let's proceed to step 1:
24 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 24

Moving on to step 2:
When dividing 64 by 24, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 16 after subtracting 48 from 64.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 24

Going ahead to step 3:
24 goes into 165 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 144 from 165 and we're left 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 next digit of our result is 8. 
Result so far: 268.0
Deduct 192 from 214 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 24

Advancing to step 5:
24 goes into 220 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 2689.0
The remainder is 4 after subtracting 216 from 220.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 24

Going ahead to step 6:
The number 24 fits into 47 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 26891.0
If we subtract 24 from 47, we 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.

Moving on to step 7:
24 can be fit into 230 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 26891.9
If we subtract 216 from 230, we 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.
Use 5 as the next digit of our solution. 
Result so far: 26891.95
Deduct 120 from 140 and we're left 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.

Moving on to step 9:
24 can be fit into 200 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 26891.958
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.

Step 10:
When dividing 80 by 24, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 26891.9583
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.

On to step 11:
The number 24 fits into 80 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 26891.95833
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 26891.95833 with a remaining 8e-06.
