396811 ÷ 29 
Our goal is to divide 396811 by 29.

Going ahead to step 1:
When dividing 3 by 29, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 29

Step 2:
29 can be fit into 39 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 29 from 39 leaves us with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 29

Advancing to step 3:
If we divide 106 by 29, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 19 after subtracting 87 from 106.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 29

Going ahead to step 4:
29 can be fit into 198 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Deduct 174 from 198 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 29

Let's proceed to step 5:
29 goes into 241 8 times with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 1368.0
If we subtract 232 from 241, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 29

Let's proceed to step 6:
29 can be fit into 91 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13683.0
The remainder is 4 after subtracting 87 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 29 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 13683.1
If we take 29 away from 40, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
29 goes into 110 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 13683.13
If we take 87 away from 110, we end up 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 9:
If we divide 230 by 29, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13683.137
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.

Moving on to step 10:
29 can be fit into 270 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 13683.1379
If we subtract 261 from 270, we get 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 11:
29 goes into 90 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13683.13793
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.

Going ahead to step 12:
The number 29 fits into 30 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 13683.137931
Deduct 29 from 30 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.

Let's proceed to step 13:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13683.137931
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
29 goes into 100 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 13683.13793103
If we take 87 away from 100, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 13683.13793103, with a leftover of 1.3e-08.
