We look at the division of 286720 by 54 
The aim is to understand the frequency of 54 in 286720.

Going ahead to step 1:
2 divided by 54 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 54

Moving on to step 2:
28 divided by 54 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 54

Let's proceed to step 3:
286 divided by 54 is 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 270 away from 286, we end up with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 54

Let's proceed to step 4:
If we divide 167 by 54, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtracting 162 from 167 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 54

Step 5:
When dividing 52 by 54, we get 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 530.0
If we take 0 away from 52, we end up with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 54

Going ahead to step 6:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 5309.0
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
54 goes into 340 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 5309.6
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 54 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 5309.62
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 5309.629
If we take 486 away from 520, we end up 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.

Let's proceed to step 10:
54 goes into 340 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 5309.6296
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 54 fits into 160 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 5309.62962
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
54 goes into 520 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 5309.629629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
When dividing 340 by 54, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 5309.6296296
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
When dividing 160 by 54, we get 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 5309.62962962
Subtract 108 from 160 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 5309.62962962 and a remainder of 5.2e-08.
