Let's divide 354909 by 24
We want to figure out the number of times 354909 can be divided by 24.

Moving on to step 1:
The number 24 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 24

Moving on to step 2:
35 divided by 24 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 24 from 35 to get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 24

Step 3:
The number 24 fits into 114 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 96 from 114 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 24

Advancing to step 4:
24 goes into 189 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtracting 168 from 189 leaves us with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 24

Let's proceed to step 5:
210 divided by 24 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1478.0
The remainder is 18 after subtracting 192 from 210.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 24

Going ahead to step 6:
24 can be fit into 189 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 14787.0
Deduct 168 from 189 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
24 goes into 210 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 14787.8
If we take 192 away from 210, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
24 can be fit into 180 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 14787.87
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
24 goes into 120 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 14787.875
Subtracting 120 from 120 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
24 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14787.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14787.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 14787.875, with a leftover of 0.0.
