345255 ÷ 29 
Our goal is to divide 345255 by 29.

Advancing to step 1:
3 divided by 29 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 29

Let's proceed to step 2:
34 divided by 29 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 29 from 34 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 29

Step 3:
29 can be fit into 55 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 29 from 55 leaves us with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 29

On to step 4:
29 can be fit into 262 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 261 from 262, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 29

On to step 5:
If we divide 15 by 29, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 1190.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 29

Advancing to step 6:
When dividing 155 by 29, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 11905.0
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:
When dividing 100 by 29, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 11905.3
If we subtract 87 from 100, we 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.

Going ahead to step 8:
29 can be fit into 130 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11905.34
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.

Step 9:
140 divided by 29 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 11905.344
If we subtract 116 from 140, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 11905.344 with a remaining 0.0024.
