We look at the division of 705339 by 54 
The aim is to understand the frequency of 54 in 705339.

Going ahead to step 1:
7 divided by 54 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 54

On to step 2:
70 divided by 54 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 54 from 70 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 54

Going ahead to step 3:
When dividing 165 by 54, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 162 away from 165, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 54

Going ahead to step 4:
33 divided by 54 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 130.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 54

On to step 5:
54 can be fit into 333 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1306.0
Deduct 324 from 333 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 54

Moving on to step 6:
When dividing 99 by 54, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 13061.0
The remainder is 45 after subtracting 54 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
If we divide 450 by 54, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 13061.8
If we subtract 432 from 450, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 54, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 13061.83
Deduct 162 from 180 and we're left 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.

Step 9:
54 goes into 180 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13061.833
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 13061.833 with a remaining 0.0018.
