We divide 17354889 by 491
The aim is to understand the frequency of 491 in 17354889.

Moving on to step 1:
1 divided by 491 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 491

Step 2:
17 divided by 491 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 491

Going ahead to step 3:
173 divided by 491 is 0 with a remainder of 173.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 173 to get 173.
Fetch the next digit (5) from the dividend, attach it to 173 and continue: 1735 / 491

Let's proceed to step 4:
When dividing 1735 by 491, we get 3 with a remainder of 262.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 262 after subtracting 1473 from 1735.
Grab the next digit (4) from the dividend, add it to 262, then carry on: 2624 / 491

Let's proceed to step 5:
If we divide 2624 by 491, we get 5 and a remainder of 169.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 2455 from 2624 and we're left with 169.
Bring next digit (8) of the dividend behind the 169 and repeat the process: 1698 / 491

On to step 6:
If we divide 1698 by 491, we get 3 and a remainder of 225.
Use 3 as the next digit of our solution. 
Result so far: 353.0
Deduct 1473 from 1698 and we're left with 225.
Fetch the next digit (8) from the dividend, attach it to 225 and continue: 2258 / 491

Going ahead to step 7:
491 can be fit into 2258 4 times, resulting in a remainder of 294.
The next digit of our result is 4. 
Result so far: 3534.0
If we subtract 1964 from 2258, we get 294.
Take the next digit (9) from the dividend and append it to 294, then repeat: 2949 / 491

Let's proceed to step 8:
2949 divided by 491 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 35346.0
If we subtract 2946 from 2949, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 491 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 35346.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 491, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 35346.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 35346.0 and a remainder of 0.3.
