We divide 225604 by 54
The aim is to understand the frequency of 54 in 225604.

Let's proceed to step 1:
54 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 54

On to step 2:
If we divide 22 by 54, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 54

Moving on to step 3:
If we divide 225 by 54, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 216 from 225, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 54

Advancing to step 4:
96 divided by 54 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 54 from 96 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 54

Step 5:
54 can be fit into 420 7 times, resulting in a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 417.0
Deduct 378 from 420 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 54

Let's proceed to step 6:
424 divided by 54 is 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 4177.0
The remainder is 46 after subtracting 378 from 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
460 divided by 54 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 4177.8
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 54, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4177.85
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 54 fits into 100 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 4177.851
The remainder is 46 after subtracting 54 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
When dividing 460 by 54, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4177.8518
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
280 divided by 54 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4177.85185
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
54 goes into 100 1 times with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 4177.851851
If we subtract 54 from 100, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
If we divide 460 by 54, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4177.8518518
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
280 divided by 54 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 4177.85185185
Subtracting 270 from 280 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4177.85185185, with a leftover of 1e-08.
