911645 divided by 54 
The aim is to understand the frequency of 54 in 911645.

On to step 1:
If we divide 9 by 54, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 54

On to step 2:
The number 54 fits into 91 1 times, leaving a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 54 away from 91, we end up with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 54

Step 3:
The number 54 fits into 371 6 times, leaving a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 324 away from 371, we end up with 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 54

On to step 4:
If we divide 476 by 54, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Subtract 432 from 476 to get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 54

Going ahead to step 5:
The number 54 fits into 444 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1688.0
If we take 432 away from 444, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 54

Advancing to step 6:
54 can be fit into 125 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 16882.0
Subtract 108 from 125 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 54 fits into 170 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 16882.3
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 54 fits into 80 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 16882.31
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
260 divided by 54 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 16882.314
If we subtract 216 from 260, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
54 can be fit into 440 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 16882.3148
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 54 fits into 80 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 16882.31481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
When dividing 260 by 54, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 16882.314814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
54 can be fit into 440 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 16882.3148148
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 16882.31481481
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 16882.31481481 and a remainder of 2.6e-08.
