256363 ÷ 81 
We want to figure out the number of times 256363 can be divided by 81.

Step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
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

Step 2:
81 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 81

Let's proceed to step 3:
256 divided by 81 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 243 from 256 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 81

Moving on to step 4:
81 goes into 133 1 times with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 52 after subtracting 81 from 133.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 81

Let's proceed to step 5:
If we divide 526 by 81, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 316.0
Deduct 486 from 526 and we're left with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 81

Step 6:
The number 81 fits into 403 4 times, leaving a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 3164.0
Subtracting 324 from 403 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
81 goes into 790 9 times with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 3164.9
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 3164.97
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
430 divided by 81 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3164.975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
81 goes into 250 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3164.9753
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 81 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 3164.9753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 3164.975308
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
If we divide 520 by 81, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 3164.9753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 3164.97530864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3164.97530864 with a remaining 1.6e-08.
