We look at the division of 349258 by 2 
We want to figure out the number of times 349258 can be divided by 2.

Step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Moving on to step 2:
14 divided by 2 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 14 from 14 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Advancing to step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 4:
2 goes into 12 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1746.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Going ahead to step 5:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 17462.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Moving on to step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 174629.0
Subtracting 18 from 18 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.

Going ahead to step 7:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 174629.0
Deduct 0 from 0 and we're left 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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 174629.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 174629.0, with a leftover of 0.0.
