We look at the division of 855578 by 87 
Our goal is to divide 855578 by 87.

Let's proceed to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 87

Advancing to step 2:
85 divided by 87 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 87

Moving on to step 3:
The number 87 fits into 855 9 times, leaving a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 783 away from 855, we end up with 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 87

Step 4:
If we divide 725 by 87, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 696 from 725 to get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 87

Going ahead to step 5:
297 divided by 87 is 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 983.0
The remainder is 36 after subtracting 261 from 297.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 87

Moving on to step 6:
368 divided by 87 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9834.0
If we subtract 348 from 368, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
If we divide 200 by 87, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 9834.2
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
If we divide 260 by 87, we get 2 and a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 9834.22
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 9834.22 with a remaining 0.086.
