We look at the division of 430442 by 81 
The aim is to understand the frequency of 81 in 430442.

Moving on 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
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 81

Step 2:
81 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 81

Moving on to step 3:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 405 from 430, we get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 81

Let's proceed to step 4:
81 can be fit into 254 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 243 from 254, we get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 81

Going ahead to step 5:
81 can be fit into 114 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 531.0
If we subtract 81 from 114, we get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 81

Let's proceed to step 6:
81 goes into 332 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5314.0
The remainder is 8 after subtracting 324 from 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 81, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 5314.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
When dividing 800 by 81, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 5314.09
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 5314.098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
620 divided by 81 is 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 5314.0987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 5314.09876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
81 can be fit into 440 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5314.098765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
If we divide 350 by 81, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 5314.0987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
When dividing 260 by 81, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 5314.09876543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 5314.09876543, and the remainder is 1.7e-08.
