We divide 645643 by 24
We want to figure out the number of times 645643 can be divided by 24.

Advancing to step 1:
24 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 24

On to step 2:
64 divided by 24 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 48 from 64 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 24

Moving on to step 3:
When dividing 165 by 24, we get 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 21 after subtracting 144 from 165.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 24

On to step 4:
216 divided by 24 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
If we subtract 216 from 216, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 24

On to step 5:
If we divide 4 by 24, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 2690.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 24

Let's proceed to step 6:
If we divide 43 by 24, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 26901.0
Deduct 24 from 43 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
190 divided by 24 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 26901.7
If we take 168 away from 190, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 24, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 26901.79
If we take 216 away from 220, we end up with 4.
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 9:
If we divide 40 by 24, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 26901.791
If we take 24 away from 40, we end up 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.

Going ahead to step 10:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 26901.7916
Deduct 144 from 160 and we're left 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.

Moving on to step 11:
160 divided by 24 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 26901.79166
If we take 144 away from 160, we end up 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.

The quotient of the division is 26901.79166, and the remainder is 1.6e-05.
