We divide 345886 by 2
Our goal is to divide 345886 by 2.

On to step 1:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 14 from 14 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Going ahead to step 3:
5 divided by 2 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Deduct 4 from 5 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Step 4:
2 can be fit into 18 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1729.0
Deduct 18 from 18 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Moving on to step 5:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 17294.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Let's proceed to step 6:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 172943.0
If we take 6 away from 6, we end up 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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 172943.0
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.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 172943.0
If we take 0 away from 0, we end up 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 172943.0 with a balance of 0.0.
