We divide 11909 by 54
The aim is to understand the frequency of 54 in 11909.

Advancing to step 1:
1 divided by 54 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 54

Moving on to step 2:
54 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 54

Moving on to step 3:
If we divide 119 by 54, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 11 after subtracting 108 from 119.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 54

Step 4:
When dividing 110 by 54, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 108 away from 110, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 54

Step 5:
When dividing 29 by 54, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 220.0
Subtract 0 from 29 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 6:
The number 54 fits into 290 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 220.5
If we take 270 away from 290, we end up 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.

Moving on to step 7:
The number 54 fits into 200 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 220.53
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
When dividing 380 by 54, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 220.537
Deduct 378 from 380 and we're left 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 9:
54 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 220.537
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 54, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 220.53703
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
If we divide 380 by 54, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 220.537037
Subtract 378 from 380 to 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.

On to step 12:
If we divide 20 by 54, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.537037
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
54 goes into 200 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 220.53703703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 220.53703703 with a balance of 3.8e-08.
