We look at the division of 25093 by 81 
We're looking to find how many times 81 goes into 25093.

Advancing to step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 81

On to step 2:
25 divided by 81 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 81

Advancing to step 3:
81 can be fit into 250 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we take 243 away from 250, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 81

Moving on to step 4:
81 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 79, we get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 81

Step 5:
When dividing 793 by 81, we get 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 309.0
If we subtract 729 from 793, 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.

Moving on to step 6:
When dividing 640 by 81, we get 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 309.7
Subtracting 567 from 640 leaves us 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.

On to step 7:
When dividing 730 by 81, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 309.79
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.

Step 8:
The number 81 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 309.79
If we take 0 away from 10, 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 9:
100 divided by 81 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 309.7901
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:
If we divide 190 by 81, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 309.79012
If we take 162 away from 190, we end up 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.

On to step 11:
280 divided by 81 is 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 309.790123
Subtracting 243 from 280 leaves us with 37.
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 12:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 309.7901234
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.

Advancing to step 13:
If we divide 460 by 81, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 309.79012345
If we subtract 405 from 460, we 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.

Our division results in 309.79012345 with a remaining 5.5e-08.
