We look at the division of 464001 by 81 
The aim is to understand the frequency of 81 in 464001.

Let's proceed to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 81

Advancing to step 2:
46 divided by 81 is 0 with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 81

Advancing to step 3:
81 can be fit into 464 5 times, resulting in a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 59 after subtracting 405 from 464.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 81

Going ahead to step 4:
If we divide 590 by 81, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 567 away from 590, we end up with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 81

Let's proceed to step 5:
The number 81 fits into 230 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 572.0
If we subtract 162 from 230, we get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 81

Moving on to step 6:
When dividing 681 by 81, we get 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 5728.0
Deduct 648 from 681 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
330 divided by 81 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 5728.4
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 81, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5728.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 81, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 5728.407
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 5728.4074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
81 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5728.4074
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 5728.407407
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
330 divided by 81 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 5728.4074074
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
81 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5728.4074074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 5728.4074074 with a remaining 6e-08.
