We look at the division of 462944 by 81 
The aim is to understand the frequency of 81 in 462944.

Moving on to step 1:
81 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 81

Step 2:
The number 81 fits into 46 0 times, leaving a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 81

On to step 3:
If we divide 462 by 81, we get 5 and a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 405 from 462 leaves us with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 81

Step 4:
81 goes into 579 7 times with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we subtract 567 from 579, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 81

Going ahead to step 5:
124 divided by 81 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 571.0
Subtract 81 from 124 to get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 81

Going ahead to step 6:
434 divided by 81 is 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 5715.0
If we take 405 away from 434, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 81, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 5715.3
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 8:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 5715.35
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 5715.358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 81, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5715.358
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 5715.35802
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5715.358024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
If we divide 560 by 81, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 5715.3580246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
81 goes into 740 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 5715.35802469
If we take 729 away from 740, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 5715.35802469, with a leftover of 1.1e-08.
