We look at the division of 665163 by 53 
The aim is to understand the frequency of 53 in 665163.

Going ahead to step 1:
53 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 53

Moving on to step 2:
If we divide 66 by 53, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 53 from 66 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 53

Moving on to step 3:
53 can be fit into 135 2 times, resulting in a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 106 away from 135, we end up with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 53

Step 4:
53 goes into 291 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we subtract 265 from 291, we get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 53

Let's proceed to step 5:
The number 53 fits into 266 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1255.0
The remainder is 1 after subtracting 265 from 266.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 53

Advancing to step 6:
When dividing 13 by 53, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 12550.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 53, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12550.2
Subtracting 106 from 130 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
53 goes into 240 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 12550.24
Deduct 212 from 240 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
53 goes into 280 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 12550.245
If we take 265 away from 280, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
53 can be fit into 150 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12550.2452
If we subtract 106 from 150, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
When dividing 440 by 53, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12550.24528
If we take 424 away from 440, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
The number 53 fits into 160 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 12550.245283
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
53 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12550.245283
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
53 can be fit into 100 1 times, resulting in a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 12550.24528301
The remainder is 47 after subtracting 53 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 12550.24528301 with a remaining 4.7e-08.
