We're dividing 11640 by 53 
The aim is to understand the frequency of 53 in 11640.

Going ahead to step 1:
When dividing 1 by 53, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 53

Going ahead to step 2:
53 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 53

Going ahead to step 3:
When dividing 116 by 53, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 106 away from 116, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 53

Step 4:
53 can be fit into 104 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 51 after subtracting 53 from 104.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 53

Going ahead to step 5:
When dividing 510 by 53, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Deduct 477 from 510 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 6:
53 can be fit into 330 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 219.6
If we subtract 318 from 330, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
When dividing 120 by 53, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 219.62
The remainder is 14 after subtracting 106 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 53 fits into 140 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 219.622
The remainder is 34 after subtracting 106 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 219.622 and a remainder of 0.0034.
