603313 ÷ 1 
We're looking to find how many times 1 goes into 603313.

On to step 1:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 0 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 603.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Advancing to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 6033.0
Subtract 3 from 3 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

On to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 60331.0
If we take 1 away from 1, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 603313.0
If we subtract 3 from 3, 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 603313.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 603313.0
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.

In conclusion, the division gives 603313.0 with a balance of 0.0.
