We look at the division of 430211 by 54 
The aim is to understand the frequency of 54 in 430211.

Step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 54

Step 2:
When dividing 43 by 54, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 54

Step 3:
The number 54 fits into 430 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 52 after subtracting 378 from 430.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 54

Moving on to step 4:
54 can be fit into 522 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we subtract 486 from 522, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 54

Advancing to step 5:
If we divide 361 by 54, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 796.0
Subtracting 324 from 361 leaves us with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 54

Let's proceed to step 6:
54 goes into 371 6 times with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 7966.0
Deduct 324 from 371 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
The number 54 fits into 470 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 7966.8
If we take 432 away from 470, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
If we divide 380 by 54, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7966.87
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 54 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7966.87
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
54 goes into 200 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 7966.8703
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7966.87037
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 54, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7966.87037
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
When dividing 200 by 54, we get 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 7966.8703703
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
54 goes into 380 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7966.87037037
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 7966.87037037 with a remaining 2e-09.
