392344 ÷ 81 
The aim is to understand the frequency of 81 in 392344.

Let's proceed to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 81

Advancing to step 2:
39 divided by 81 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 81

Moving on to step 3:
When dividing 392 by 81, we get 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 324 from 392 to get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 81

Step 4:
If we divide 683 by 81, we get 8 and a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 35 after subtracting 648 from 683.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 81

Going ahead to step 5:
81 goes into 354 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 484.0
If we take 324 away from 354, we end up with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 81

Let's proceed to step 6:
If we divide 304 by 81, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 4843.0
If we subtract 243 from 304, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
81 goes into 610 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 4843.7
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
81 goes into 430 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4843.75
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
250 divided by 81 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 4843.753
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
70 divided by 81 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4843.753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
81 goes into 700 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 4843.75308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
When dividing 520 by 81, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 4843.753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4843.7530864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 4843.75308641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 4843.75308641, with a leftover of 7.9e-08.
