We divide 748809 by 54
The aim is to understand the frequency of 54 in 748809.

Going ahead to step 1:
When dividing 7 by 54, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 54

Advancing to step 2:
If we divide 74 by 54, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 54 from 74, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 54

Let's proceed to step 3:
54 can be fit into 208 3 times, resulting in a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 162 from 208 to get 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 54

On to step 4:
If we divide 468 by 54, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtract 432 from 468 to get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 54

Moving on to step 5:
360 divided by 54 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1386.0
Deduct 324 from 360 and we're left with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 54

Moving on to step 6:
54 can be fit into 369 6 times, resulting in a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 13866.0
Subtracting 324 from 369 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 54 fits into 450 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 13866.8
Subtracting 432 from 450 leaves us 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.

Moving on to step 8:
54 goes into 180 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13866.83
Deduct 162 from 180 and we're left 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.

Let's proceed to step 9:
If we divide 180 by 54, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 13866.833
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.

Our division results in 13866.833 with a remaining 0.0018.
