We look at the division of 28585 by 81 
We want to figure out the number of times 28585 can be divided by 81.

Going ahead to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 81

Advancing to step 2:
When dividing 28 by 81, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 81

Let's proceed to step 3:
285 divided by 81 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 243 from 285 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 81

Step 4:
If we divide 428 by 81, we get 5 and a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 405 from 428 leaves us with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 81

Let's proceed to step 5:
81 can be fit into 235 2 times, resulting in a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 352.0
If we take 162 away from 235, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 6:
81 can be fit into 730 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 352.9
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 81 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 352.9
Subtract 0 from 10 to 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.

Going ahead to step 8:
The number 81 fits into 100 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 352.901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
190 divided by 81 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 352.9012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 81, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 352.90123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 352.901234
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
81 goes into 460 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 352.9012345
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 352.90123456
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 352.90123456 and a remainder of 6.4e-08.
