855485 ÷ 86 
We want to divide 855485 by 86.

Advancing to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Step 2:
86 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 86

Advancing to step 3:
86 goes into 855 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 774 away from 855, we end up with 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 86

Advancing to step 4:
814 divided by 86 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 774 from 814, we get 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 86

Let's proceed to step 5:
The number 86 fits into 408 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 994.0
If we subtract 344 from 408, we get 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 86

Going ahead to step 6:
If we divide 645 by 86, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 9947.0
Subtracting 602 from 645 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
86 can be fit into 430 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 9947.5
Subtract 430 from 430 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.

Moving on to step 8:
0 divided by 86 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9947.5
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.

Going ahead to step 9:
The number 86 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9947.5
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.

Our division results in 9947.5 with a remaining 0.0.
