We divide 627309 by 53
The aim is to understand the frequency of 53 in 627309.

Step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 53

Moving on to step 2:
If we divide 62 by 53, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 53 away from 62, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 53

Advancing to step 3:
53 can be fit into 97 1 times, resulting in a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 44 after subtracting 53 from 97.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 53

Moving on to step 4:
The number 53 fits into 443 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 118.0
The remainder is 19 after subtracting 424 from 443.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 53

Advancing to step 5:
The number 53 fits into 190 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1183.0
Subtracting 159 from 190 leaves us with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 53

Advancing to step 6:
319 divided by 53 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 11836.0
Subtract 318 from 319 to 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.

Step 7:
10 divided by 53 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 11836.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
53 can be fit into 100 1 times, resulting in a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 11836.01
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.

On to step 9:
470 divided by 53 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 11836.018
Deduct 424 from 470 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
53 can be fit into 460 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 11836.0188
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 11836.0188 with a remainder of 0.00036.
