408859 ÷ 24 
We're looking to find how many times 24 goes into 408859.

Going ahead to step 1:
If we divide 4 by 24, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 24

On to step 2:
40 divided by 24 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 24 from 40 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 24

Going ahead to step 3:
24 can be fit into 168 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 168 from 168 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 24

Advancing to step 4:
The number 24 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 24

Advancing to step 5:
When dividing 85 by 24, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 1703.0
Subtracting 72 from 85 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 24

Let's proceed to step 6:
139 divided by 24 is 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 17035.0
Deduct 120 from 139 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 24 fits into 190 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 17035.7
The remainder is 22 after subtracting 168 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
If we divide 220 by 24, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 17035.79
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
24 goes into 40 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 17035.791
Deduct 24 from 40 and we're left 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.

Moving on to step 10:
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: 17035.7916
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.

Let's proceed to step 11:
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: 17035.79166
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 quotient of the division is 17035.79166, and the remainder is 1.6e-05.
