Let's divide 26781146 by 491
The aim is to understand the frequency of 491 in 26781146.

Step 1:
If we divide 2 by 491, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 491

Let's proceed to step 2:
26 divided by 491 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 491

Advancing to step 3:
When dividing 267 by 491, we get 0 with a remainder of 267.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 267 leaves us with 267.
Append the next digit (8) from the dividend to 267 and continue with: 2678 / 491

Moving on to step 4:
The number 491 fits into 2678 5 times, leaving a remainder of 223.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2455 from 2678 leaves us with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 491

Going ahead to step 5:
2231 divided by 491 is 4 with a remainder of 267.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 1964 away from 2231, we end up with 267.
Fetch the next digit (1) from the dividend, attach it to 267 and continue: 2671 / 491

Step 6:
2671 divided by 491 is 5 with a remainder of 216.
Use 5 as the next digit of our solution. 
Result so far: 545.0
If we subtract 2455 from 2671, we get 216.
Include the next digit (4) from the dividend after 216, then repeat: 2164 / 491

Going ahead to step 7:
491 goes into 2164 4 times with a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 5454.0
If we take 1964 away from 2164, we end up with 200.
Fetch the next digit (6) from the dividend, attach it to 200 and continue: 2006 / 491

Advancing to step 8:
2006 divided by 491 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 54544.0
Deduct 1964 from 2006 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 491 fits into 420 0 times, leaving a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 54544.0
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
When dividing 4200 by 491, we get 8 with a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 54544.08
Subtracting 3928 from 4200 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 11:
When dividing 2720 by 491, we get 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 54544.085
Subtracting 2455 from 2720 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 12:
If we divide 2650 by 491, we get 5 and a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 54544.0855
If we subtract 2455 from 2650, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Our division results in 54544.0855 with a remaining 0.00195.
