345801 divided by 2 
Let's see how many times 2 fits into 345801.

On to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Advancing to step 2:
14 divided by 2 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 14 from 14, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Let's proceed to step 3:
If we divide 5 by 2, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtracting 4 from 5 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Let's proceed to step 4:
2 can be fit into 18 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1729.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Let's proceed to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17290.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Step 6:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 172900.0
Deduct 0 from 1 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.

On to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 172900.5
Subtracting 10 from 10 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.

Advancing to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 172900.5
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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 172900.5
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.

After the division, we end up with 172900.5 and a remainder of 0.0.
