129205 ÷ 24 
Let's see how many times 24 fits into 129205.

Going ahead to step 1:
24 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 24

Step 2:
The number 24 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 24

Advancing to step 3:
When dividing 129 by 24, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 120 from 129 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 24

Moving on to step 4:
When dividing 92 by 24, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 53.0
If we take 72 away from 92, we end up with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 24

Moving on to step 5:
The number 24 fits into 200 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 538.0
Subtracting 192 from 200 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 24

Moving on to step 6:
The number 24 fits into 85 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 5383.0
Subtract 72 from 85 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.

On to step 7:
130 divided by 24 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5383.5
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 24 fits into 100 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 5383.54
Subtract 96 from 100 to 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.

Going ahead to step 9:
40 divided by 24 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 5383.541
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.

Advancing to step 10:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 5383.5416
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.

On to step 11:
The number 24 fits into 160 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5383.54166
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 5383.54166 with a remainder of 1.6e-05.
