We're dividing 304226 by 53 
The aim is to understand the frequency of 53 in 304226.

On to step 1:
53 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 53

Advancing to step 2:
When dividing 30 by 53, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 53

Moving on to step 3:
When dividing 304 by 53, we get 5 with a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 265 from 304 leaves us with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 53

On to step 4:
392 divided by 53 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtract 371 from 392 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 53

Going ahead to step 5:
When dividing 212 by 53, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 574.0
If we subtract 212 from 212, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 53

Advancing to step 6:
53 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 5740.0
Deduct 0 from 6 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 53 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 5740.1
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
If we divide 70 by 53, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 5740.11
The remainder is 17 after subtracting 53 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 5740.11 with a remaining 0.017.
