We're dividing 399049 by 24 
We want to figure out the number of times 399049 can be divided by 24.

Going ahead to step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 24

Let's proceed to step 2:
The number 24 fits into 39 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 24 from 39 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 24

Moving on to step 3:
The number 24 fits into 159 6 times, leaving a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 144 from 159 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 24

Step 4:
When dividing 150 by 24, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
If we subtract 144 from 150, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 24

Moving on to step 5:
64 divided by 24 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1662.0
Subtracting 48 from 64 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 24

Let's proceed to step 6:
24 goes into 169 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 16627.0
Subtract 168 from 169 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 24 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16627.0
Subtract 0 from 10 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 8:
100 divided by 24 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 16627.04
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
24 can be fit into 40 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 16627.041
If we subtract 24 from 40, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 24, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16627.0416
If we subtract 144 from 160, we get 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:
When dividing 160 by 24, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16627.04166
Subtract 144 from 160 to get 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 16627.04166 with a remainder of 1.6e-05.
