Let's divide 838788 by 54
The aim is to understand the frequency of 54 in 838788.

Step 1:
8 divided by 54 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 54

Advancing to step 2:
If we divide 83 by 54, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 54 away from 83, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 54

Step 3:
When dividing 298 by 54, we get 5 with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 28 after subtracting 270 from 298.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 54

Advancing to step 4:
If we divide 287 by 54, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Deduct 270 from 287 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 54

Step 5:
54 goes into 178 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 1553.0
If we take 162 away from 178, we end up with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 54

Advancing to step 6:
168 divided by 54 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 15533.0
Subtracting 162 from 168 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 54 fits into 60 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 15533.1
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 15533.11
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 15533.11 with a remainder of 0.006.
