We're dividing 54716305 by 438 
The aim is to understand the frequency of 438 in 54716305.

Advancing to step 1:
The number 438 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 438

On to step 2:
The number 438 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 438

Step 3:
If we divide 547 by 438, we get 1 and a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 438 from 547 leaves us with 109.
Take the next digit (1) from the dividend and append it to 109, then repeat: 1091 / 438

Going ahead to step 4:
The number 438 fits into 1091 2 times, leaving a remainder of 215.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 876 from 1091 and we're left with 215.
Take the next digit (6) from the dividend and append it to 215, then repeat: 2156 / 438

Let's proceed to step 5:
438 goes into 2156 4 times with a remainder of 404.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 1752 from 2156 leaves us with 404.
Take the next digit (3) from the dividend and append it to 404, then repeat: 4043 / 438

Moving on to step 6:
When dividing 4043 by 438, we get 9 with a remainder of 101.
The next digit of our result is 9. 
Result so far: 1249.0
Subtracting 3942 from 4043 leaves us with 101.
Fetch the next digit (0) from the dividend, attach it to 101 and continue: 1010 / 438

Let's proceed to step 7:
The number 438 fits into 1010 2 times, leaving a remainder of 134.
The next digit of our result is 2. 
Result so far: 12492.0
The remainder is 134 after subtracting 876 from 1010.
Take the next digit (5) from the dividend and append it to 134, then repeat: 1345 / 438

Moving on to step 8:
438 can be fit into 1345 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 124923.0
Deduct 1314 from 1345 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
The number 438 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 124923.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
The number 438 fits into 3100 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 124923.07
Subtracting 3066 from 3100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
If we divide 340 by 438, we get 0 and a remainder of 340.
The next digit of our result is 0. 
Result so far: 124923.07
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
When dividing 3400 by 438, we get 7 with a remainder of 334.
Write down 7 as next digit of the result. 
Result so far: 124923.0707
The remainder is 334 after subtracting 3066 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 13:
3340 divided by 438 is 7 with a remainder of 274.
The next digit of our result is 7. 
Result so far: 124923.07077
If we subtract 3066 from 3340, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

After the division, we end up with 124923.07077 and a remainder of 0.000274.
