We're dividing 622403 by 54 
The aim is to understand the frequency of 54 in 622403.

Advancing to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 54

Let's proceed to step 2:
62 divided by 54 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 54 from 62, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 54

Moving on to step 3:
54 can be fit into 82 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 54 from 82 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 54

Moving on to step 4:
The number 54 fits into 284 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 270 from 284 to get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 54

Going ahead to step 5:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
Subtract 108 from 140 to get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 54

Let's proceed to step 6:
54 can be fit into 323 5 times, resulting in a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 11525.0
Subtracting 270 from 323 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 54 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 11525.9
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
The number 54 fits into 440 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 11525.98
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11525.981
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 54, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 11525.9814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
54 goes into 440 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 11525.98148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
54 goes into 80 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 11525.981481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 54 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11525.9814814
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
54 can be fit into 440 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11525.98148148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 11525.98148148 with a remainder of 8e-09.
