437815 ÷ 2 
We want to divide 437815 by 2.

Moving on to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

On to step 2:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 2 from 3 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Step 3:
If we divide 17 by 2, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 218.0
The remainder is 1 after subtracting 16 from 17.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Advancing to step 4:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 2189.0
If we subtract 18 from 18, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

On to step 5:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 21890.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 6:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 218907.0
Deduct 14 from 15 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.

Advancing to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 218907.5
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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 218907.5
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.

Going ahead to step 9:
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: 218907.5
Subtracting 0 from 0 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.

In conclusion, the division gives 218907.5 with a balance of 0.0.
