The aim is to understand the frequency of 249 in 54407873.

Going ahead to step 1:
249 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 249

Advancing to step 2:
The number 249 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 249

Let's proceed to step 3:
When dividing 544 by 249, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 498 from 544 to get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 249

Going ahead to step 4:
The number 249 fits into 460 1 times, leaving a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 249 from 460 leaves us with 211.
Append the next digit (7) from the dividend to 211 and continue with: 2117 / 249

Advancing to step 5:
249 goes into 2117 8 times with a remainder of 125.
The next digit of our result is 8. 
Result so far: 218.0
Subtracting 1992 from 2117 leaves us with 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 249

Going ahead to step 6:
1258 divided by 249 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 2185.0
Deduct 1245 from 1258 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 249

Advancing to step 7:
If we divide 137 by 249, we get 0 and a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 21850.0
If we take 0 away from 137, we end up with 137.
Include the next digit (3) from the dividend after 137, then repeat: 1373 / 249

Let's proceed to step 8:
1373 divided by 249 is 5 with a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 218505.0
The remainder is 128 after subtracting 1245 from 1373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
1280 divided by 249 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 218505.5
If we subtract 1245 from 1280, we get 35.
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 10:
249 goes into 350 1 times with a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 218505.51
If we subtract 249 from 350, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 11:
1010 divided by 249 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 218505.514
Subtracting 996 from 1010 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
249 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 218505.514
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
249 can be fit into 1400 5 times, resulting in a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 218505.51405
Subtracting 1245 from 1400 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 14:
When dividing 1550 by 249, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 218505.514056
Subtract 1494 from 1550 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 15:
The number 249 fits into 560 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 218505.5140562
If we subtract 498 from 560, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 16:
249 goes into 620 2 times with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 218505.51405622
Subtract 498 from 620 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 218505.51405622 with a balance of 1.22e-07.
