204517 divided by 81 
We want to figure out the number of times 204517 can be divided by 81.

On to step 1:
2 divided by 81 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 81

On to step 2:
81 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 81

Let's proceed to step 3:
If we divide 204 by 81, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 162 from 204 and we're left with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 81

Let's proceed to step 4:
81 goes into 425 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 405 from 425 and we're left with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 81

Advancing to step 5:
The number 81 fits into 201 2 times, leaving a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we subtract 162 from 201, we get 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 81

Going ahead to step 6:
81 can be fit into 397 4 times, resulting in a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 2524.0
If we take 324 away from 397, 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.

Moving on to step 7:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2524.9
Deduct 729 from 730 and we're left 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.

Moving on to step 8:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2524.9
The remainder is 10 after subtracting 0 from 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 9:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2524.901
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 10:
190 divided by 81 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2524.9012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 81 fits into 280 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 2524.90123
Subtract 243 from 280 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
370 divided by 81 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 2524.901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 81 fits into 460 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 2524.9012345
Subtracting 405 from 460 leaves us with 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 14:
When dividing 550 by 81, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 2524.90123456
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 2524.90123456 with a remaining 6.4e-08.
