We look at the division of 320329 by 53 
The aim is to understand the frequency of 53 in 320329.

Moving on to step 1:
If we divide 3 by 53, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 53

On to step 2:
The number 53 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 53

Advancing to step 3:
53 goes into 320 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 318 from 320 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 53

Moving on to step 4:
The number 53 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 53

Moving on to step 5:
If we divide 232 by 53, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 604.0
If we take 212 away from 232, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 53

Let's proceed to step 6:
53 can be fit into 209 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 6043.0
If we take 159 away from 209, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 6043.9
Subtracting 477 from 500 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
When dividing 230 by 53, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 6043.94
Deduct 212 from 230 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 53 fits into 180 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 6043.943
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
If we divide 210 by 53, we get 3 and a remainder of 51.
The next digit of our result is 3. 
Result so far: 6043.9433
Subtracting 159 from 210 leaves us 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.

Our division results in 6043.9433 with a remaining 0.00051.
