We look at the division of 912966 by 54 
The aim is to understand the frequency of 54 in 912966.

Moving on to step 1:
The number 54 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 54

Let's proceed to step 2:
If we divide 91 by 54, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 54 from 91 and we're left with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 54

On to step 3:
If we divide 372 by 54, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 324 from 372 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 54

Going ahead to step 4:
If we divide 489 by 54, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtract 486 from 489 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 54

On to step 5:
When dividing 36 by 54, we get 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 1690.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 54

Step 6:
If we divide 366 by 54, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 16906.0
If we take 324 away from 366, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
The number 54 fits into 420 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 16906.7
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
54 goes into 420 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 16906.77
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 16906.77 with a remainder of 0.042.
