We're dividing 643376 by 24 
We want to figure out the number of times 643376 can be divided by 24.

Going ahead to step 1:
When dividing 6 by 24, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 24

Advancing to step 2:
24 goes into 64 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 48 away from 64, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 24

Advancing to step 3:
24 can be fit into 163 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 19 after subtracting 144 from 163.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 24

Going ahead to step 4:
24 goes into 193 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
If we take 192 away from 193, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 24

Step 5:
24 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 2680.0
Subtract 0 from 17 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 24

Advancing to step 6:
If we divide 176 by 24, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 26807.0
If we subtract 168 from 176, 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.

On to step 7:
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: 26807.3
If we subtract 72 from 80, 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.

Let's proceed to step 8:
24 goes into 80 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 26807.33
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.

The quotient of the division is 26807.33, and the remainder is 0.008.
