We're dividing 352470 by 54 
The aim is to understand the frequency of 54 in 352470.

Going ahead to step 1:
54 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 54

Advancing to step 2:
The number 54 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 54

Going ahead to step 3:
54 can be fit into 352 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 324 from 352 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 54

Going ahead to step 4:
The number 54 fits into 284 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 65.0
If we take 270 away from 284, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 54

Moving on to step 5:
54 can be fit into 147 2 times, resulting in a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
If we subtract 108 from 147, we get 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 54

Moving on to step 6:
54 can be fit into 390 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 6527.0
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
54 can be fit into 120 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 6527.2
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
54 goes into 120 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 6527.22
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6527.22, with a leftover of 0.012.
