We're dividing 869886 by 85 
Let's see how many times 85 fits into 869886.

Advancing to step 1:
85 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 85

Going ahead to step 2:
If we divide 86 by 85, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 85 from 86, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 85

On to step 3:
85 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 85

Let's proceed to step 4:
85 goes into 198 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 170 from 198 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 85

Going ahead to step 5:
85 goes into 288 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 1023.0
If we take 255 away from 288, we end up with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 85

Step 6:
85 can be fit into 336 3 times, resulting in a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 10233.0
If we take 255 away from 336, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
810 divided by 85 is 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 10233.9
Subtracting 765 from 810 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.

Let's proceed to step 8:
85 can be fit into 450 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10233.95
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
When dividing 250 by 85, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 10233.952
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
If we divide 800 by 85, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 10233.9529
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 85, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 10233.95294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 10233.952941
If we subtract 85 from 100, we 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.

Step 13:
If we divide 150 by 85, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10233.9529411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 10233.9529411 and a remainder of 6.5e-07.
