We divide 17239021 by 491
The aim is to understand the frequency of 491 in 17239021.

Going ahead to step 1:
The number 491 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 491

Advancing to 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
Subtracting 0 from 17 leaves us with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 491

Going ahead to step 3:
172 divided by 491 is 0 with a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 172, we end up with 172.
Fetch the next digit (3) from the dividend, attach it to 172 and continue: 1723 / 491

Let's proceed to step 4:
1723 divided by 491 is 3 with a remainder of 250.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1473 from 1723 and we're left with 250.
Grab the next digit (9) from the dividend, add it to 250, then carry on: 2509 / 491

Let's proceed to step 5:
The number 491 fits into 2509 5 times, leaving a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 2455 from 2509 leaves us with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 491

On to step 6:
The number 491 fits into 540 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 351.0
If we take 491 away from 540, we end up with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 491

Let's proceed to step 7:
When dividing 492 by 491, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3511.0
Subtracting 491 from 492 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 491

Let's proceed to step 8:
11 divided by 491 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 35110.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
The number 491 fits into 110 0 times, leaving a remainder of 110.
The next digit of our result is 0. 
Result so far: 35110.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
If we divide 1100 by 491, we get 2 and a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 35110.02
If we take 982 away from 1100, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 11:
When dividing 1180 by 491, we get 2 with a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 35110.022
The remainder is 198 after subtracting 982 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

In conclusion, the division gives 35110.022 with a balance of 0.0198.
