405209 divided by 29 
Our goal is to divide 405209 by 29.

On to step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 29

Let's proceed to step 2:
29 goes into 40 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 29 from 40.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 29

Let's proceed to step 3:
115 divided by 29 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 87 from 115 to get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 29

On to step 4:
When dividing 282 by 29, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we take 261 away from 282, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 29

Moving on to step 5:
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: 1397.0
If we take 203 away from 210, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 29

Let's proceed to step 6:
29 can be fit into 79 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 13972.0
The remainder is 21 after subtracting 58 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 29 fits into 210 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 13972.7
The remainder is 7 after subtracting 203 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 29, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 13972.72
The remainder is 12 after subtracting 58 from 70.
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 9:
29 goes into 120 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 13972.724
Deduct 116 from 120 and we're left 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.

Let's proceed to step 10:
The number 29 fits into 40 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 13972.7241
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.

Step 11:
If we divide 110 by 29, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 13972.72413
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.

Advancing to step 12:
The number 29 fits into 230 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 13972.724137
If we take 203 away from 230, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
The number 29 fits into 270 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 13972.7241379
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
29 can be fit into 90 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13972.72413793
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 13972.72413793 with a balance of 3e-09.
