We look at the division of 65057909 by 353 
The aim is to understand the frequency of 353 in 65057909.

Advancing to step 1:
The number 353 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 353

Step 2:
353 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 353

Step 3:
If we divide 650 by 353, we get 1 and a remainder of 297.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 353 from 650, we get 297.
Grab the next digit (5) from the dividend, add it to 297, then carry on: 2975 / 353

Step 4:
If we divide 2975 by 353, we get 8 and a remainder of 151.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 2824 away from 2975, we end up with 151.
Bring next digit (7) of the dividend behind the 151 and repeat the process: 1517 / 353

Let's proceed to step 5:
353 goes into 1517 4 times with a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
The remainder is 105 after subtracting 1412 from 1517.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 353

Step 6:
353 goes into 1059 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 1843.0
Subtracting 1059 from 1059 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 353

Advancing to step 7:
353 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18430.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 353

Advancing to step 8:
The number 353 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 184300.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
353 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 184300.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
If we divide 900 by 353, we get 2 and a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 184300.02
Deduct 706 from 900 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 11:
When dividing 1940 by 353, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 184300.025
The remainder is 175 after subtracting 1765 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
If we divide 1750 by 353, we get 4 and a remainder of 338.
Put 4 as the next digit of the answer. 
Result so far: 184300.0254
If we take 1412 away from 1750, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 13:
When dividing 3380 by 353, we get 9 with a remainder of 203.
Use 9 as the next digit of our solution. 
Result so far: 184300.02549
If we subtract 3177 from 3380, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 14:
353 goes into 2030 5 times with a remainder of 265.
The next digit of our result is 5. 
Result so far: 184300.025495
Subtracting 1765 from 2030 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.

On to step 15:
When dividing 2650 by 353, we get 7 with a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 184300.0254957
If we take 2471 away from 2650, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 16:
When dividing 1790 by 353, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 184300.02549575
Subtract 1765 from 1790 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 184300.02549575 with a remaining 2.5e-08.
