We're dividing 362425 by 81 
The aim is to understand the frequency of 81 in 362425.

Going ahead to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 81

Going ahead to step 2:
36 divided by 81 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 81

On to step 3:
81 goes into 362 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 324 away from 362, we end up with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 81

Going ahead to step 4:
81 can be fit into 384 4 times, resulting in a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 324 from 384 leaves us with 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 81

Let's proceed to step 5:
81 goes into 602 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 447.0
Subtracting 567 from 602 leaves us with 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 81

Advancing to step 6:
The number 81 fits into 355 4 times, leaving a remainder of 31.
The next digit of our result is 4. 
Result so far: 4474.0
The remainder is 31 after subtracting 324 from 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
When dividing 310 by 81, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 4474.3
If we take 243 away from 310, we end up 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.

Going ahead to step 8:
670 divided by 81 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 4474.38
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.

Going ahead to step 9:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 4474.382
Subtract 162 from 220 to 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.

Advancing to step 10:
The number 81 fits into 580 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4474.3827
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 81, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 4474.38271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

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: 4474.382716
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.

Going ahead to step 13:
The number 81 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4474.382716
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
When dividing 400 by 81, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4474.38271604
If we subtract 324 from 400, we get 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 4474.38271604, with a leftover of 7.6e-08.
