We divide 873980 by 85
We're looking to find how many times 85 goes into 873980.

Moving on to step 1:
85 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
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

Moving on to step 2:
87 divided by 85 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 85 from 87 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 85

Moving on to step 3:
23 divided by 85 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 23 leaves us with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 85

Step 4:
When dividing 239 by 85, we get 2 with a remainder of 69.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 170 from 239 and we're left with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 85

Advancing to step 5:
85 can be fit into 698 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1028.0
If we subtract 680 from 698, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 85

Let's proceed to step 6:
When dividing 180 by 85, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 10282.0
If we take 170 away from 180, 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.

Advancing to step 7:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 10282.1
Subtract 85 from 100 to 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 8:
When dividing 150 by 85, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 10282.11
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 10282.11, with a leftover of 0.065.
