We're dividing 66390905 by 24 
Our goal is to divide 66390905 by 24.

Let's proceed 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
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 24

Moving on to step 2:
24 goes into 66 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 48 from 66 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 24

Step 3:
When dividing 183 by 24, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 168 from 183 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 24

Going ahead to step 4:
If we divide 159 by 24, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 276.0
If we subtract 144 from 159, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 24

On to step 5:
The number 24 fits into 150 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 2766.0
If we take 144 away from 150, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 24

Moving on to step 6:
The number 24 fits into 69 2 times, leaving a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 27662.0
Deduct 48 from 69 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 24

Advancing to step 7:
24 goes into 210 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 276628.0
If we take 192 away from 210, we end up with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 24

Going ahead to step 8:
185 divided by 24 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2766287.0
The remainder is 17 after subtracting 168 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
170 divided by 24 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2766287.7
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
When dividing 20 by 24, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2766287.7
Deduct 0 from 20 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.

Step 11:
24 goes into 200 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2766287.708
If we take 192 away from 200, we end up 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.

Going ahead to step 12:
24 goes into 80 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 2766287.7083
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.

Moving on to step 13:
When dividing 80 by 24, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 2766287.70833
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.

The quotient of the division is 2766287.70833, and the remainder is 8e-06.
