171129 divided by 4 
We're looking to find how many times 4 goes into 171129.

Going ahead to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 4

Step 2:
4 can be fit into 17 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 16 away from 17, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Step 3:
The number 4 fits into 11 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 8 from 11 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Advancing to step 4:
When dividing 31 by 4, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtracting 28 from 31 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 4

Step 5:
4 goes into 32 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4278.0
If we take 32 away from 32, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Moving on to step 6:
4 goes into 9 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 42782.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 4, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 42782.2
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42782.25
If we subtract 20 from 20, we get 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 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42782.25
Subtract 0 from 0 to get 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 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42782.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 42782.25 with a balance of 0.0.
