877970 divided by 85 
We want to divide 877970 by 85.

Going ahead to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 85

On to step 2:
85 goes into 87 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 85 from 87 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 85

Advancing to step 3:
When dividing 27 by 85, we get 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 27 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 85

Step 4:
85 can be fit into 279 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 103.0
If we take 255 away from 279, we end up with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 85

Moving on to step 5:
When dividing 247 by 85, we get 2 with a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 1032.0
Subtract 170 from 247 to get 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 85

Step 6:
85 goes into 770 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 10329.0
Deduct 765 from 770 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10329.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 10329.05
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
85 goes into 750 8 times with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 10329.058
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 85 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10329.0588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 10329.0588 and a remainder of 0.0002.
