759791 divided by 81 
The aim is to understand the frequency of 81 in 759791.

On to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 81

Advancing to step 2:
75 divided by 81 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (9) from the dividend to 75 and continue with: 759 / 81

Step 3:
If we divide 759 by 81, we get 9 and a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 729 away from 759, we end up with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 81

Going ahead to step 4:
The number 81 fits into 307 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 93.0
Subtract 243 from 307 to get 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 81

On to step 5:
The number 81 fits into 649 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
If we take 648 away from 649, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 81

Let's proceed to step 6:
81 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 9380.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 81, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 9380.1
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
81 goes into 290 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 9380.13
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
If we divide 470 by 81, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9380.135
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
650 divided by 81 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 9380.1358
Subtracting 648 from 650 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
20 divided by 81 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9380.1358
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 81, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 9380.135802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
81 can be fit into 380 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9380.1358024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
When dividing 560 by 81, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 9380.13580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 9380.13580246 with a balance of 7.4e-08.
