66857746 divided by 24 
We want to figure out the number of times 66857746 can be divided by 24.

Going ahead to step 1:
The number 24 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 24

Moving on to step 2:
24 can be fit into 66 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 48 from 66 leaves us with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 24

Let's proceed to step 3:
The number 24 fits into 188 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 168 from 188 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 24

Moving on to step 4:
The number 24 fits into 205 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
If we take 192 away from 205, we end up with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 24

Step 5:
24 goes into 137 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 2785.0
Deduct 120 from 137 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 24

Moving on to step 6:
When dividing 177 by 24, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 27857.0
Deduct 168 from 177 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 24

Moving on to step 7:
The number 24 fits into 94 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 278573.0
Deduct 72 from 94 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 24

Advancing to step 8:
24 can be fit into 226 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 2785739.0
Subtract 216 from 226 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 24 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2785739.4
Deduct 96 from 100 and we're left 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.

Advancing to step 10:
40 divided by 24 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 2785739.41
Deduct 24 from 40 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.

Advancing to step 11:
160 divided by 24 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 2785739.416
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.

Let's proceed to step 12:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 2785739.4166
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.

The final result is 2785739.4166 with a remainder of 0.00016.
