We're dividing 870205 by 81 
We're looking to find how many times 81 goes into 870205.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 81

Moving on to step 2:
81 goes into 87 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 81 from 87 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 81

On to step 3:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 60 and we're left with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 81

Going ahead to step 4:
81 goes into 602 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtract 567 from 602 to get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 81

Step 5:
If we divide 350 by 81, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 1074.0
If we take 324 away from 350, we end up with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 81

Let's proceed to step 6:
81 goes into 265 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 10743.0
Subtracting 243 from 265 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 10743.2
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
81 can be fit into 580 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 10743.27
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
If we divide 130 by 81, we get 1 and a remainder of 49.
The next digit of our result is 1. 
Result so far: 10743.271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
If we divide 490 by 81, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 10743.2716
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10743.2716
Deduct 0 from 40 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.

Let's proceed to step 12:
81 goes into 400 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 10743.271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
When dividing 760 by 81, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 10743.2716049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
When dividing 310 by 81, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 10743.27160493
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 10743.27160493 and a remainder of 6.7e-08.
