171255 ÷ 29 
Let's see how many times 29 fits into 171255.

Step 1:
If we divide 1 by 29, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 29

Advancing to step 2:
When dividing 17 by 29, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 29

Moving on to step 3:
The number 29 fits into 171 5 times, leaving a remainder of 26.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 145 from 171, we get 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 29

On to step 4:
If we divide 262 by 29, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 261 from 262 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 29

Moving on to step 5:
15 divided by 29 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 29

On to step 6:
If we divide 155 by 29, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5905.0
Subtracting 145 from 155 leaves us 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 7:
29 goes into 100 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 5905.3
If we take 87 away from 100, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
29 can be fit into 130 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 5905.34
If we subtract 116 from 130, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 29, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 5905.344
If we take 116 away from 140, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 5905.344 with a remainder of 0.0024.
