We look at the division of 395141 by 54 
The aim is to understand the frequency of 54 in 395141.

Let's proceed to step 1:
3 divided by 54 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 54

Advancing to step 2:
54 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 54

On to step 3:
395 divided by 54 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 17 after subtracting 378 from 395.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 54

On to step 4:
54 goes into 171 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 162 from 171 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 54

Step 5:
54 goes into 94 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 731.0
If we take 54 away from 94, we end up with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 54

Advancing to step 6:
54 can be fit into 401 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7317.0
Subtract 378 from 401 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 54 fits into 230 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 7317.4
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 54 fits into 140 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 7317.42
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 54, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7317.425
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 54 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 7317.4259
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
54 goes into 140 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 7317.42592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 54 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7317.425925
Subtracting 270 from 320 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
If we divide 500 by 54, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 7317.4259259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
If we divide 140 by 54, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 7317.42592592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 7317.42592592 with a remainder of 3.2e-08.
