873189 ÷ 85 
Our goal is to divide 873189 by 85.

Advancing to step 1:
The number 85 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 85

On to step 2:
The number 85 fits into 87 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 85 from 87, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 85

Moving on to step 3:
When dividing 23 by 85, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 85

Moving on to step 4:
When dividing 231 by 85, we get 2 with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 61 after subtracting 170 from 231.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 85

Let's proceed to step 5:
618 divided by 85 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1027.0
Subtract 595 from 618 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 85

On to step 6:
239 divided by 85 is 2 with a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 10272.0
If we take 170 away from 239, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
When dividing 690 by 85, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 10272.8
If we take 680 away from 690, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 85 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 10272.81
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.

Moving on to step 9:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 10272.811
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 10272.811 with a remaining 0.0065.
