393473 ÷ 29 
Our goal is to divide 393473 by 29.

Let's proceed to step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 29

Advancing to step 2:
29 can be fit into 39 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 29 from 39 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 29

Going ahead to step 3:
103 divided by 29 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 87 away from 103, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 29

Going ahead to step 4:
When dividing 164 by 29, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 135.0
If we take 145 away from 164, we end up with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 29

Let's proceed to step 5:
The number 29 fits into 197 6 times, leaving a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 1356.0
The remainder is 23 after subtracting 174 from 197.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 29

On to step 6:
If we divide 233 by 29, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 13568.0
Deduct 232 from 233 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.

Advancing to step 7:
10 divided by 29 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13568.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13568.03
Subtract 87 from 100 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 29 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 13568.034
Subtract 116 from 130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
29 goes into 140 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 13568.0344
If we subtract 116 from 140, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 13568.0344 with a remainder of 0.00024.
