431129 divided by 29 
Let's see how many times 29 fits into 431129.

Step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 29

Going ahead to step 2:
When dividing 43 by 29, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 29 from 43, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 29

Step 3:
29 goes into 141 4 times with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 116 from 141, we get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 29

Moving on to step 4:
29 can be fit into 251 8 times, resulting in a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 148.0
The remainder is 19 after subtracting 232 from 251.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 29

Step 5:
192 divided by 29 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1486.0
The remainder is 18 after subtracting 174 from 192.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 29

On to step 6:
29 goes into 189 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 14866.0
Subtract 174 from 189 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.

On to step 7:
29 goes into 150 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14866.5
The remainder is 5 after subtracting 145 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 29, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 14866.51
If we subtract 29 from 50, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
When dividing 210 by 29, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 14866.517
Deduct 203 from 210 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
70 divided by 29 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 14866.5172
Subtract 58 from 70 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
29 can be fit into 120 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 14866.51724
If we take 116 away from 120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 29 fits into 40 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 14866.517241
If we subtract 29 from 40, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
29 goes into 110 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 14866.5172413
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
When dividing 230 by 29, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 14866.51724137
The remainder is 27 after subtracting 203 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 14866.51724137 and a remainder of 2.7e-08.
