We look at the division of 218472 by 53 
The aim is to understand the frequency of 53 in 218472.

Moving on to step 1:
If we divide 2 by 53, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 53

Moving on to step 2:
The number 53 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 53

Let's proceed to step 3:
If we divide 218 by 53, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 212 from 218 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 53

Going ahead to step 4:
53 can be fit into 64 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 53 from 64, we get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 53

Step 5:
53 can be fit into 117 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 412.0
Deduct 106 from 117 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 53

Step 6:
When dividing 112 by 53, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4122.0
If we subtract 106 from 112, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 53, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4122.1
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 53 fits into 70 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 4122.11
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 4122.11 with a remainder of 0.017.
