We're dividing 863385 by 85 
Let's see how many times 85 fits into 863385.

On to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 85

On to step 2:
The number 85 fits into 86 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 85 from 86 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 85

Going ahead to step 3:
When dividing 13 by 85, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 85

Let's proceed to step 4:
85 goes into 133 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 85 from 133 and we're left with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 85

Let's proceed to step 5:
85 can be fit into 488 5 times, resulting in a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 1015.0
The remainder is 63 after subtracting 425 from 488.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 85

On to step 6:
When dividing 635 by 85, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 10157.0
Deduct 595 from 635 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
85 goes into 400 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 10157.4
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 10157.47
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 85, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10157.47
If we take 0 away from 50, we end up 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 10:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 10157.4705
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.

Let's proceed to step 11:
When dividing 750 by 85, we get 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 10157.47058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10157.470588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 10157.470588 with a remainder of 2e-06.
