129356 ÷ 29 
We want to divide 129356 by 29.

Advancing to step 1:
1 divided by 29 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 29

Step 2:
The number 29 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our 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 / 29

Let's proceed to step 3:
When dividing 129 by 29, we get 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 116 away from 129, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 29

Advancing to step 4:
29 goes into 133 4 times with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 116 away from 133, we end up with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 29

On to step 5:
When dividing 175 by 29, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
Subtract 174 from 175 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 29

Moving on to step 6:
29 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 4460.0
Deduct 0 from 16 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.

Moving on to step 7:
If we divide 160 by 29, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4460.5
Subtract 145 from 160 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 29, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4460.55
Subtracting 145 from 150 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 4460.55 with a remaining 0.005.
