We look at the division of 332907 by 53 
The aim is to understand the frequency of 53 in 332907.

Going ahead to step 1:
When dividing 3 by 53, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 53

Moving on to step 2:
If we divide 33 by 53, we get 0 and a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 53

Step 3:
When dividing 332 by 53, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 318 from 332 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 53

On to step 4:
149 divided by 53 is 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtract 106 from 149 to get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 53

Moving on to step 5:
53 can be fit into 430 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 628.0
If we take 424 away from 430, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 53

Moving on to step 6:
If we divide 67 by 53, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 6281.0
If we take 53 away from 67, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
53 can be fit into 140 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 6281.2
If we subtract 106 from 140, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
53 goes into 340 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 6281.26
Subtracting 318 from 340 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
53 goes into 220 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 6281.264
If we take 212 away from 220, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
53 goes into 80 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 6281.2641
If we subtract 53 from 80, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
The number 53 fits into 270 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6281.26415
Subtracting 265 from 270 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
50 divided by 53 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 6281.26415
Subtracting 0 from 50 leaves us 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 13:
When dividing 500 by 53, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 6281.2641509
If we take 477 away from 500, we end up 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.

Let's proceed to step 14:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 6281.26415094
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.

After the division, we end up with 6281.26415094 and a remainder of 1.8e-08.
