We divide 247729 by 81
The aim is to understand the frequency of 81 in 247729.

Advancing to step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 81

On to step 2:
The number 81 fits into 24 0 times, leaving a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 81

Advancing to step 3:
247 divided by 81 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 243 from 247 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 81

Moving on to step 4:
When dividing 47 by 81, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 81

Going ahead to step 5:
81 can be fit into 472 5 times, resulting in a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Deduct 405 from 472 and we're left with 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 81

Going ahead to step 6:
81 goes into 679 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 3058.0
Subtract 648 from 679 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
When dividing 310 by 81, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3058.3
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 8:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 3058.38
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
81 goes into 220 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 3058.382
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3058.3827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
The number 81 fits into 130 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3058.38271
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
81 goes into 490 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3058.382716
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
81 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3058.382716
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 3058.38271604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 3058.38271604, with a leftover of 7.6e-08.
