We look at the division of 17311790 by 301 
The aim is to understand the frequency of 301 in 17311790.

Let's proceed to step 1:
The number 301 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.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 301

On to step 2:
If we divide 17 by 301, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 301

Going ahead to step 3:
301 can be fit into 173 0 times, resulting in a remainder of 173.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 173, we get 173.
Take the next digit (1) from the dividend and append it to 173, then repeat: 1731 / 301

On to step 4:
The number 301 fits into 1731 5 times, leaving a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1505 from 1731, we get 226.
Grab the next digit (1) from the dividend, add it to 226, then carry on: 2261 / 301

Moving on to step 5:
The number 301 fits into 2261 7 times, leaving a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtract 2107 from 2261 to get 154.
Append the next digit (7) from the dividend to 154 and continue with: 1547 / 301

Step 6:
The number 301 fits into 1547 5 times, leaving a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
If we take 1505 away from 1547, we end up with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 301

Step 7:
301 goes into 429 1 times with a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 5751.0
Subtracting 301 from 429 leaves us with 128.
Grab the next digit (0) from the dividend, add it to 128, then carry on: 1280 / 301

Going ahead to step 8:
301 can be fit into 1280 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 57514.0
Subtracting 1204 from 1280 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
760 divided by 301 is 2 with a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 57514.2
Subtracting 602 from 760 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
If we divide 1580 by 301, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 57514.25
Deduct 1505 from 1580 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
301 can be fit into 750 2 times, resulting in a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 57514.252
If we subtract 602 from 750, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
The number 301 fits into 1480 4 times, leaving a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 57514.2524
Subtracting 1204 from 1480 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 13:
If we divide 2760 by 301, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 57514.25249
Deduct 2709 from 2760 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 14:
301 goes into 510 1 times with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 57514.252491
If we take 301 away from 510, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 15:
The number 301 fits into 2090 6 times, leaving a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 57514.2524916
Subtracting 1806 from 2090 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 16:
If we divide 2840 by 301, we get 9 and a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 57514.25249169
Subtracting 2709 from 2840 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final result is 57514.25249169 with a remainder of 1.31e-07.
