We're dividing 54504304 by 251 
The aim is to understand the frequency of 251 in 54504304.

Going ahead to step 1:
251 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 251

Going ahead to step 2:
54 divided by 251 is 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 251

Step 3:
251 goes into 545 2 times with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 502 from 545, we get 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 251

Going ahead to step 4:
251 goes into 430 1 times with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 251 from 430 to get 179.
Bring next digit (4) of the dividend behind the 179 and repeat the process: 1794 / 251

Moving on to step 5:
When dividing 1794 by 251, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 217.0
If we subtract 1757 from 1794, we get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 251

Let's proceed to step 6:
The number 251 fits into 373 1 times, leaving a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 2171.0
Subtract 251 from 373 to get 122.
Bring next digit (0) of the dividend behind the 122 and repeat the process: 1220 / 251

Going ahead to step 7:
251 goes into 1220 4 times with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 21714.0
If we subtract 1004 from 1220, we get 216.
Bring next digit (4) of the dividend behind the 216 and repeat the process: 2164 / 251

Going ahead to step 8:
The number 251 fits into 2164 8 times, leaving a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 217148.0
Subtracting 2008 from 2164 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 9:
When dividing 1560 by 251, we get 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 217148.6
Subtract 1506 from 1560 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
When dividing 540 by 251, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 217148.62
If we take 502 away from 540, we end up 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.

Let's proceed to step 11:
380 divided by 251 is 1 with a remainder of 129.
The next digit of our result is 1. 
Result so far: 217148.621
Subtract 251 from 380 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
1290 divided by 251 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 217148.6215
The remainder is 35 after subtracting 1255 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
251 goes into 350 1 times with a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 217148.62151
Subtracting 251 from 350 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 14:
If we divide 990 by 251, we get 3 and a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 217148.621513
Deduct 753 from 990 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 15:
251 can be fit into 2370 9 times, resulting in a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 217148.6215139
Deduct 2259 from 2370 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 16:
251 can be fit into 1110 4 times, resulting in a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 217148.62151394
Subtracting 1004 from 1110 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 217148.62151394 with a balance of 1.06e-07.
