We look at the division of 343448 by 1 
Our goal is to divide 343448 by 1.

On to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 34.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Let's proceed to step 3:
3 divided by 1 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

On to step 4:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 3434.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 5:
1 goes into 4 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 34344.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Moving on to step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 343448.0
The remainder is 0 after subtracting 8 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 343448.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 343448.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 343448.0 with a balance of 0.0.
