We divide 646436 by 24
Let's see how many times 24 fits into 646436.

Let's proceed to step 1:
When dividing 6 by 24, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 24

Let's proceed to step 2:
24 goes into 64 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 48 from 64 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 24

Step 3:
If we divide 166 by 24, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 144 from 166 leaves us with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 24

Advancing to step 4:
If we divide 224 by 24, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 269.0
Subtract 216 from 224 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 24

Moving on to step 5:
The number 24 fits into 83 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 2693.0
If we subtract 72 from 83, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 24

Going ahead to step 6:
The number 24 fits into 116 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 26934.0
Subtracting 96 from 116 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.

Step 7:
If we divide 200 by 24, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 26934.8
Deduct 192 from 200 and we're left 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.

Let's proceed to step 8:
When dividing 80 by 24, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 26934.83
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.

Advancing to step 9:
If we divide 80 by 24, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 26934.833
Deduct 72 from 80 and we're left 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 final outcome is 26934.833, with a leftover of 0.0008.
