We look at the division of 81456565 by 427 
The aim is to understand the frequency of 427 in 81456565.

On to step 1:
427 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 427

Advancing to step 2:
81 divided by 427 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 427

Advancing to step 3:
The number 427 fits into 814 1 times, leaving a remainder of 387.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 387 after subtracting 427 from 814.
Take the next digit (5) from the dividend and append it to 387, then repeat: 3875 / 427

Step 4:
The number 427 fits into 3875 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 3843 from 3875 leaves us with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 427

Going ahead to step 5:
427 can be fit into 326 0 times, resulting in a remainder of 326.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we take 0 away from 326, we end up with 326.
Grab the next digit (5) from the dividend, add it to 326, then carry on: 3265 / 427

Advancing to step 6:
If we divide 3265 by 427, we get 7 and a remainder of 276.
The next digit of our result is 7. 
Result so far: 1907.0
The remainder is 276 after subtracting 2989 from 3265.
Append the next digit (6) from the dividend to 276 and continue with: 2766 / 427

Going ahead to step 7:
The number 427 fits into 2766 6 times, leaving a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 19076.0
If we subtract 2562 from 2766, we get 204.
Include the next digit (5) from the dividend after 204, then repeat: 2045 / 427

Moving on to step 8:
The number 427 fits into 2045 4 times, leaving a remainder of 337.
The next digit of our result is 4. 
Result so far: 190764.0
If we take 1708 away from 2045, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 9:
427 goes into 3370 7 times with a remainder of 381.
Write down 7 as next digit of the result. 
Result so far: 190764.7
Deduct 2989 from 3370 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 10:
427 can be fit into 3810 8 times, resulting in a remainder of 394.
Put 8 as the next digit of the answer. 
Result so far: 190764.78
Subtracting 3416 from 3810 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 11:
427 goes into 3940 9 times with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 190764.789
Subtract 3843 from 3940 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 12:
If we divide 970 by 427, we get 2 and a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 190764.7892
Subtracting 854 from 970 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
When dividing 1160 by 427, we get 2 with a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 190764.78922
Deduct 854 from 1160 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Our division results in 190764.78922 with a remaining 0.000306.
