We're dividing 319457 by 2 
We want to divide 319457 by 2.

Step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Let's proceed to step 2:
2 goes into 11 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 10 from 11 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

On to step 3:
19 divided by 2 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we take 18 away from 19, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Let's proceed to step 4:
14 divided by 2 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1597.0
Subtracting 14 from 14 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Advancing to step 5:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 15972.0
Subtract 4 from 5 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Moving on to step 6:
2 can be fit into 17 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 159728.0
The remainder is 1 after subtracting 16 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 159728.5
Deduct 10 from 10 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.

Advancing to step 8:
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: 159728.5
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.

Let's proceed to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 159728.5
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.

Our division results in 159728.5 with a remaining 0.0.
