969526 divided by 81 
The aim is to understand the frequency of 81 in 969526.

Let's proceed to step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 81

On to step 2:
81 can be fit into 96 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 81 from 96.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 81

Moving on to step 3:
If we divide 159 by 81, we get 1 and a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 81 away from 159, we end up with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 81

Going ahead to step 4:
The number 81 fits into 785 9 times, leaving a remainder of 56.
The next digit of our result is 9. 
Result so far: 119.0
Subtract 729 from 785 to get 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 81

Advancing to step 5:
81 can be fit into 562 6 times, resulting in a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.0
Subtracting 486 from 562 leaves us with 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 81

Advancing to step 6:
If we divide 766 by 81, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 11969.0
If we subtract 729 from 766, we 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.

On to step 7:
81 can be fit into 370 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 11969.4
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.

Let's proceed to step 8:
460 divided by 81 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 11969.45
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
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: 11969.456
Deduct 486 from 550 and we're left 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.

Let's proceed to step 10:
81 can be fit into 640 7 times, resulting in a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 11969.4567
Deduct 567 from 640 and we're left 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.

Advancing to step 11:
730 divided by 81 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11969.45679
Subtracting 729 from 730 leaves us 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.

On to step 12:
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: 11969.45679
Deduct 0 from 10 and we're left 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.

Step 13:
If we divide 100 by 81, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11969.4567901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
81 can be fit into 190 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 11969.45679012
Subtracting 162 from 190 leaves us 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.

In conclusion, the division gives 11969.45679012 with a balance of 2.8e-08.
