We look at the division of 302598 by 1 
We're looking to find how many times 1 goes into 302598.

Step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 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: 3025.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 5:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 30259.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Let's proceed to step 6:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 302598.0
Subtract 8 from 8 to 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.

Step 7:
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: 302598.0
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 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 302598.0
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.

Our division results in 302598.0 with a remaining 0.0.
