We're dividing 936648 by 54 
The aim is to understand the frequency of 54 in 936648.

Let's proceed to step 1:
When dividing 9 by 54, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 54

Step 2:
54 goes into 93 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 54 from 93 to get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 54

Going ahead to step 3:
54 goes into 396 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 378 from 396 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 54

Moving on to step 4:
54 goes into 186 3 times with a remainder of 24.
The next digit of our result is 3. 
Result so far: 173.0
Subtract 162 from 186 to get 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 54

On to step 5:
54 goes into 244 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1734.0
If we subtract 216 from 244, we get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 54

On to step 6:
If we divide 288 by 54, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 17345.0
Subtract 270 from 288 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 54, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 17345.3
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
54 can be fit into 180 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 17345.33
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 17345.33 and a remainder of 0.018.
