We divide 67524 by 81
The aim is to understand the frequency of 81 in 67524.

Step 1:
81 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 81

Advancing to step 2:
67 divided by 81 is 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 81

On to step 3:
If we divide 675 by 81, we get 8 and a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 648 from 675, we get 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 81

Going ahead to step 4:
81 can be fit into 272 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 243 from 272, we get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 81

Advancing to step 5:
294 divided by 81 is 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 833.0
Subtract 243 from 294 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 6:
510 divided by 81 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 833.6
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
When dividing 240 by 81, we get 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 833.62
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 833.629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
If we divide 510 by 81, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 833.6296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
81 goes into 240 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 833.62962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 833.629629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
If we divide 510 by 81, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 833.6296296
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
81 goes into 240 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 833.62962962
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 833.62962962 with a remaining 7.8e-08.
