We divide 99585 by 87
We want to divide 99585 by 87.

On to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 87

Step 2:
87 can be fit into 99 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 87 away from 99, we end up with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 87

Step 3:
The number 87 fits into 125 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 11.0
If we take 87 away from 125, we end up with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 87

Let's proceed to step 4:
87 goes into 388 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 114.0
Deduct 348 from 388 and we're left with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 87

Advancing to step 5:
If we divide 405 by 87, we get 4 and a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 1144.0
If we take 348 away from 405, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 6:
570 divided by 87 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1144.6
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
480 divided by 87 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1144.65
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
If we divide 450 by 87, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1144.655
Subtract 435 from 450 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 1144.655 with a remaining 0.0015.
