We look at the division of 908746 by 54 
The aim is to understand the frequency of 54 in 908746.

Moving on to step 1:
The number 54 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 54

On to step 2:
If we divide 90 by 54, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 54 from 90 to get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 54

Going ahead to step 3:
The number 54 fits into 368 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 324 from 368 and we're left with 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 54

Step 4:
54 can be fit into 447 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 168.0
The remainder is 15 after subtracting 432 from 447.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 54

Let's proceed to step 5:
When dividing 154 by 54, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1682.0
Deduct 108 from 154 and we're left with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 54

Let's proceed to step 6:
If we divide 466 by 54, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 16828.0
Deduct 432 from 466 and we're left 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 7:
When dividing 340 by 54, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 16828.6
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.

Advancing to step 8:
54 goes into 160 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 16828.62
If we subtract 108 from 160, we 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.

Let's proceed to step 9:
If we divide 520 by 54, we get 9 and a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 16828.629
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.

Moving on to step 10:
The number 54 fits into 340 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 16828.6296
Subtracting 324 from 340 leaves us 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.

On to step 11:
When dividing 160 by 54, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 16828.62962
Deduct 108 from 160 and we're left 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.

Going ahead to step 12:
If we divide 520 by 54, we get 9 and a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 16828.629629
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:
54 can be fit into 340 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 16828.6296296
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.

Moving on to step 14:
54 can be fit into 160 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 16828.62962962
Deduct 108 from 160 and we're left 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.

The final outcome is 16828.62962962, with a leftover of 5.2e-08.
