We're dividing 91063189 by 491 
The aim is to understand the frequency of 491 in 91063189.

Moving on to step 1:
If we divide 9 by 491, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 491

Step 2:
491 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 491

On to step 3:
If we divide 910 by 491, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 419 after subtracting 491 from 910.
Include the next digit (6) from the dividend after 419, then repeat: 4196 / 491

Let's proceed to step 4:
The number 491 fits into 4196 8 times, leaving a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 268 after subtracting 3928 from 4196.
Include the next digit (3) from the dividend after 268, then repeat: 2683 / 491

Step 5:
491 goes into 2683 5 times with a remainder of 228.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Subtracting 2455 from 2683 leaves us with 228.
Fetch the next digit (1) from the dividend, attach it to 228 and continue: 2281 / 491

Going ahead to step 6:
When dividing 2281 by 491, we get 4 with a remainder of 317.
The number 4 becomes the next digit in our result. 
Result so far: 1854.0
If we subtract 1964 from 2281, we get 317.
Append the next digit (8) from the dividend to 317 and continue with: 3178 / 491

Moving on to step 7:
3178 divided by 491 is 6 with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 18546.0
If we subtract 2946 from 3178, we get 232.
Grab the next digit (9) from the dividend, add it to 232, then carry on: 2329 / 491

Let's proceed to step 8:
491 can be fit into 2329 4 times, resulting in a remainder of 365.
Put 4 as the next digit of the answer. 
Result so far: 185464.0
Subtracting 1964 from 2329 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 9:
3650 divided by 491 is 7 with a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 185464.7
The remainder is 213 after subtracting 3437 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 10:
The number 491 fits into 2130 4 times, leaving a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 185464.74
If we take 1964 away from 2130, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
The number 491 fits into 1660 3 times, leaving a remainder of 187.
The next digit of our result is 3. 
Result so far: 185464.743
Subtracting 1473 from 1660 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 12:
491 can be fit into 1870 3 times, resulting in a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 185464.7433
The remainder is 397 after subtracting 1473 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The final result is 185464.7433 with a remainder of 0.00397.
