We're dividing 115587 by 1 
We want to divide 115587 by 1.

Let's proceed to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Going ahead to step 2:
When dividing 1 by 1, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 1 from 1 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Step 3:
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: 115.0
Deduct 5 from 5 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Going ahead to step 4:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1155.0
Subtracting 5 from 5 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 5:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 11558.0
Subtract 8 from 8 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 6:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 115587.0
Deduct 7 from 7 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.

On to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 115587.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 115587.0
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.

After the division, we end up with 115587.0 and a remainder of 0.0.
