667437 ÷ 2 
Let's see how many times 2 fits into 667437.

Step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 2:
If we divide 6 by 2, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 6 from 6 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

On to step 3:
If we divide 7 by 2, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 333.0
Deduct 6 from 7 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Let's proceed to step 4:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 3337.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Moving on to step 5:
3 divided by 2 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 33371.0
Subtracting 2 from 3 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Moving on to step 6:
If we divide 17 by 2, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 333718.0
Subtract 16 from 17 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 333718.5
If we subtract 10 from 10, 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 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 333718.5
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.

Moving on to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 333718.5
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.

The final result is 333718.5 with a remainder of 0.0.
