958062 divided by 81 
The aim is to understand the frequency of 81 in 958062.

Step 1:
If we divide 9 by 81, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 81

Let's proceed to step 2:
95 divided by 81 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 95 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 81

On to step 3:
81 can be fit into 148 1 times, resulting in a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 67 after subtracting 81 from 148.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 81

On to step 4:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 118.0
The remainder is 22 after subtracting 648 from 670.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 81

Advancing to step 5:
81 can be fit into 226 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 1182.0
Subtracting 162 from 226 leaves us with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 81

Let's proceed to step 6:
When dividing 642 by 81, we get 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 11827.0
The remainder is 75 after subtracting 567 from 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 7:
When dividing 750 by 81, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 11827.9
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
When dividing 210 by 81, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 11827.92
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 81, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 11827.925
The remainder is 75 after subtracting 405 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
The number 81 fits into 750 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 11827.9259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
The number 81 fits into 210 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 11827.92592
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 11827.925925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
750 divided by 81 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 11827.9259259
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
The number 81 fits into 210 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 11827.92592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 11827.92592592 with a remainder of 4.8e-08.
