We look at the division of 399085 by 24 
Let's see how many times 24 fits into 399085.

Let's proceed to step 1:
3 divided by 24 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 24

On to step 2:
The number 24 fits into 39 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 24 from 39 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 24

Let's proceed to step 3:
24 goes into 159 6 times with 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.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 24

Step 4:
When dividing 150 by 24, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 166.0
If we take 144 away from 150, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 24

On to step 5:
24 can be fit into 68 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1662.0
If we subtract 48 from 68, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 24

On to step 6:
If we divide 205 by 24, we get 8 and a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 16628.0
Subtract 192 from 205 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 24 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 16628.5
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 24, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 16628.54
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 goes into 40 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 16628.541
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: 16628.5416
Subtracting 144 from 160 leaves us 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:
24 goes into 160 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 16628.54166
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.

The final result is 16628.54166 with a remainder of 1.6e-05.
