We look at the division of 219454 by 53 
The aim is to understand the frequency of 53 in 219454.

Advancing to step 1:
53 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 53

Advancing to step 2:
The number 53 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 53

On to step 3:
219 divided by 53 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 212 from 219 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 53

Step 4:
The number 53 fits into 74 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 53 from 74 leaves us with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 53

Moving on to step 5:
53 can be fit into 215 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 414.0
Subtracting 212 from 215 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 53

Going ahead to step 6:
53 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 4140.0
Subtracting 0 from 34 leaves us with 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 7:
53 can be fit into 340 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4140.6
If we subtract 318 from 340, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 53, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4140.64
The remainder is 8 after subtracting 212 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
53 goes into 80 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 4140.641
Subtracting 53 from 80 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
If we divide 270 by 53, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4140.6415
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.

Advancing to step 11:
When dividing 50 by 53, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4140.6415
Deduct 0 from 50 and we're left 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.

Step 12:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 4140.641509
Subtracting 477 from 500 leaves us 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.

Advancing to step 13:
230 divided by 53 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4140.6415094
Subtracting 212 from 230 leaves us 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.

On to step 14:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 4140.64150943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 4140.64150943 with a remainder of 2.1e-08.
