670363 ÷ 2 
Let's see how many times 2 fits into 670363.

Going ahead to step 1:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

On to step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 6 from 7, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Advancing to step 3:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 335.0
The remainder is 0 after subtracting 10 from 10.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Step 4:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3351.0
Deduct 2 from 3 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Moving on to step 5:
If we divide 16 by 2, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 33518.0
If we take 16 away from 16, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Moving on to step 6:
When dividing 3 by 2, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 335181.0
Deduct 2 from 3 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:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 335181.5
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.

On to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 335181.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 335181.5
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 335181.5 with a remaining 0.0.
