Let's divide 391577 by 24
We're looking to find how many times 24 goes into 391577.

Advancing to step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 24

Moving on to step 2:
24 goes into 39 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 24 from 39 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 24

Going ahead to step 3:
24 can be fit into 151 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 144 from 151 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 24

Moving on to step 4:
24 goes into 75 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Deduct 72 from 75 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 24

On to step 5:
If we divide 37 by 24, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1631.0
Subtracting 24 from 37 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 24

On to step 6:
24 goes into 137 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 16315.0
If we subtract 120 from 137, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 24, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 16315.7
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
24 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 16315.7
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.

On to step 9:
24 goes into 200 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 16315.708
If we subtract 192 from 200, we 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.

Advancing to step 10:
If we divide 80 by 24, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 16315.7083
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.

Let's proceed to step 11:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 16315.70833
If we subtract 72 from 80, we 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 final outcome is 16315.70833, with a leftover of 8e-06.
