251937 divided by 54 
The aim is to understand the frequency of 54 in 251937.

Let's proceed to step 1:
The number 54 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 54

Advancing to step 2:
If we divide 25 by 54, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 54

Going ahead to step 3:
The number 54 fits into 251 4 times, leaving a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 216 from 251 leaves us with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 54

Step 4:
359 divided by 54 is 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 324 from 359 and we're left with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 54

Moving on to step 5:
54 can be fit into 353 6 times, resulting in a remainder of 29.
The next digit of our result is 6. 
Result so far: 466.0
Subtract 324 from 353 to get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 54

Moving on to step 6:
54 goes into 297 5 times with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 4665.0
The remainder is 27 after subtracting 270 from 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
270 divided by 54 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4665.5
If we take 270 away from 270, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 54 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4665.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
54 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4665.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4665.5, and the remainder is 0.0.
