315215 ÷ 2 
Our goal is to divide 315215 by 2.

Let's proceed to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Moving on to step 2:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 10 from 11 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 157.0
The remainder is 1 after subtracting 14 from 15.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Advancing to step 4:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1576.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Let's proceed to step 5:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 15760.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Moving on to step 6:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 157607.0
If we take 14 away from 15, we end up 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.

Let's proceed to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 157607.5
The remainder is 0 after subtracting 10 from 10.
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:
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: 157607.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 157607.5
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.

The final result is 157607.5 with a remainder of 0.0.
