300075 ÷ 1 
Let's see how many times 1 fits into 300075.

Advancing to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 0, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 3:
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: 300.0
Subtract 0 from 0 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

On to step 4:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3000.0
Subtract 0 from 0 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Advancing to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 30007.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 300075.0
Subtracting 5 from 5 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 300075.0
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.

Moving on to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 300075.0
Subtract 0 from 0 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.

In conclusion, the division gives 300075.0 with a balance of 0.0.
