We're dividing 303518 by 1 
Let's see how many times 1 fits into 303518.

On to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 0, we end up with 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.
Use 3 as the next digit of our solution. 
Result so far: 303.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 4:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3035.0
The remainder is 0 after subtracting 5 from 5.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 5:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 30351.0
If we take 1 away from 1, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 303518.0
If we subtract 8 from 8, 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.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 303518.0
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.

Let's proceed to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 303518.0
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.

The quotient of the division is 303518.0, and the remainder is 0.0.
