12691493 divided by 427 
The aim is to understand the frequency of 427 in 12691493.

Let's proceed to step 1:
1 divided by 427 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 427

Moving on to step 2:
427 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 427

On to step 3:
427 goes into 126 0 times with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 427

On to step 4:
The number 427 fits into 1269 2 times, leaving a remainder of 415.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 854 from 1269 leaves us with 415.
Bring next digit (1) of the dividend behind the 415 and repeat the process: 4151 / 427

On to step 5:
The number 427 fits into 4151 9 times, leaving a remainder of 308.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 3843 away from 4151, we end up with 308.
Append the next digit (4) from the dividend to 308 and continue with: 3084 / 427

Step 6:
The number 427 fits into 3084 7 times, leaving a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
If we subtract 2989 from 3084, we get 95.
Bring next digit (9) of the dividend behind the 95 and repeat the process: 959 / 427

Going ahead to step 7:
427 can be fit into 959 2 times, resulting in a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 2972.0
If we subtract 854 from 959, we get 105.
Bring next digit (3) of the dividend behind the 105 and repeat the process: 1053 / 427

Let's proceed to step 8:
If we divide 1053 by 427, we get 2 and a remainder of 199.
The next digit of our result is 2. 
Result so far: 29722.0
If we subtract 854 from 1053, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 9:
1990 divided by 427 is 4 with a remainder of 282.
The number 4 becomes the next digit in our result. 
Result so far: 29722.4
Subtracting 1708 from 1990 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
If we divide 2820 by 427, we get 6 and a remainder of 258.
Record the quotient 6 as the next digit in the result. 
Result so far: 29722.46
If we take 2562 away from 2820, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 11:
The number 427 fits into 2580 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 29722.466
If we subtract 2562 from 2580, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 29722.466 with a remainder of 0.0018.
