390088 divided by 24 
Our goal is to divide 390088 by 24.

Step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 24

Step 2:
24 goes into 39 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 24 from 39, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 24

Step 3:
The number 24 fits into 150 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 144 from 150 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 24

On to step 4:
60 divided by 24 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 48 from 60 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 24

Going ahead to step 5:
128 divided by 24 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 1625.0
Subtract 120 from 128 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 24

On to step 6:
88 divided by 24 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 16253.0
If we take 72 away from 88, we end up 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 7:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16253.6
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.

On to step 8:
The number 24 fits into 160 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 16253.66
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 16253.66 with a remainder of 0.016.
