We divide 826882 by 81
The aim is to understand the frequency of 81 in 826882.

On to step 1:
81 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 81

Going ahead to step 2:
82 divided by 81 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 82 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 81

Step 3:
The number 81 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 81

Going ahead to step 4:
If we divide 168 by 81, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 162 from 168 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 81

On to step 5:
81 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 1020.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 81

Going ahead to step 6:
81 can be fit into 682 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 10208.0
If we take 648 away from 682, we end up with 34.
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 7:
If we divide 340 by 81, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 10208.4
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 10208.41
Deduct 81 from 160 and we're left 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.

Moving on to step 9:
790 divided by 81 is 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 10208.419
The remainder is 61 after subtracting 729 from 790.
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 10:
The number 81 fits into 610 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 10208.4197
Subtract 567 from 610 to 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.

Let's proceed to step 11:
81 goes into 430 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10208.41975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 10208.419753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
If we divide 70 by 81, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10208.419753
Deduct 0 from 70 and we're left 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.

On to step 14:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 10208.41975308
Deduct 648 from 700 and we're left 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.

The final result is 10208.41975308 with a remainder of 5.2e-08.
