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
If we subtract 3 from 3, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Let's proceed to step 2:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Advancing to step 3:
1 goes into 7 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 387.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3875.0
Subtract 5 from 5 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 38758.0
Subtract 8 from 8 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 387585.0
If we take 5 away from 5, 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.

Step 7:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 387585.0
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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 387585.0
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 387585.0 with a balance of 0.0.
