Let's divide 335745 by 81
The aim is to understand the frequency of 81 in 335745.

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
If we subtract 0 from 3, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 81

Going ahead to step 2:
If we divide 33 by 81, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 81

Let's proceed to step 3:
If we divide 335 by 81, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 324 from 335 and we're left with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 81

Step 4:
81 goes into 117 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 36 after subtracting 81 from 117.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 81

Let's proceed to step 5:
81 can be fit into 364 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 414.0
If we take 324 away from 364, we end up with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 81

Step 6:
81 goes into 405 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4145.0
If we subtract 405 from 405, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 81, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4145.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 81, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4145.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4145.0 with a remaining 0.0.
