We look at the division of 417310 by 53 
The aim is to understand the frequency of 53 in 417310.

Advancing to step 1:
4 divided by 53 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 53

Step 2:
When dividing 41 by 53, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 53

Advancing to step 3:
53 can be fit into 417 7 times, resulting in a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 371 from 417 leaves us with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 53

On to step 4:
53 goes into 463 8 times with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 424 from 463 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 53

Let's proceed to step 5:
391 divided by 53 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 787.0
Deduct 371 from 391 and we're left with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 53

Moving on to step 6:
200 divided by 53 is 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 7873.0
The remainder is 41 after subtracting 159 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
53 goes into 410 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 7873.7
Subtract 371 from 410 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
390 divided by 53 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7873.77
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 7873.77, with a leftover of 0.019.
