We're dividing 150320 by 54 
The aim is to understand the frequency of 54 in 150320.

Let's proceed to step 1:
The number 54 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 54

Moving on to step 2:
When dividing 15 by 54, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 54

Step 3:
150 divided by 54 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 108 from 150 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 54

Let's proceed to step 4:
423 divided by 54 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 378 from 423 to get 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 54

Moving on to step 5:
If we divide 452 by 54, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
The remainder is 20 after subtracting 432 from 452.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 54

Moving on to step 6:
54 goes into 200 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 2783.0
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2783.7
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
54 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2783.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 54, we get 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 2783.703
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
54 goes into 380 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 2783.7037
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 54, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2783.7037
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
When dividing 200 by 54, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 2783.703703
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 54 fits into 380 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2783.7037037
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
54 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2783.7037037
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 2783.7037037 with a remaining 2e-08.
