We look at the division of 795294 by 81 
The aim is to understand the frequency of 81 in 795294.

Advancing to step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 81

Moving on to step 2:
When dividing 79 by 81, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 81

Advancing to step 3:
If we divide 795 by 81, we get 9 and a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 66 after subtracting 729 from 795.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 81

On to step 4:
662 divided by 81 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtracting 648 from 662 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 81

Advancing to step 5:
When dividing 149 by 81, we get 1 with a remainder of 68.
The next digit of our result is 1. 
Result so far: 981.0
Subtracting 81 from 149 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 81

On to step 6:
The number 81 fits into 684 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9818.0
The remainder is 36 after subtracting 648 from 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
81 goes into 360 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9818.4
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
The number 81 fits into 360 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 9818.44
If we take 324 away from 360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 9818.44, with a leftover of 0.036.
