We're dividing 54423964 by 304 
The aim is to understand the frequency of 304 in 54423964.

Moving on to step 1:
If we divide 5 by 304, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 304

Advancing to step 2:
If we divide 54 by 304, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 304

Let's proceed to step 3:
When dividing 544 by 304, we get 1 with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 304 from 544 leaves us with 240.
Include the next digit (2) from the dividend after 240, then repeat: 2402 / 304

On to step 4:
2402 divided by 304 is 7 with a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 2128 from 2402 leaves us with 274.
Fetch the next digit (3) from the dividend, attach it to 274 and continue: 2743 / 304

On to step 5:
304 can be fit into 2743 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we subtract 2736 from 2743, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 304

On to step 6:
304 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 1790.0
Subtracting 0 from 79 leaves us with 79.
Fetch the next digit (6) from the dividend, attach it to 79 and continue: 796 / 304

Going ahead to step 7:
When dividing 796 by 304, we get 2 with a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 17902.0
Deduct 608 from 796 and we're left with 188.
Take the next digit (4) from the dividend and append it to 188, then repeat: 1884 / 304

Advancing to step 8:
304 can be fit into 1884 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 179026.0
If we subtract 1824 from 1884, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
If we divide 600 by 304, we get 1 and a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 179026.1
Subtracting 304 from 600 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 10:
If we divide 2960 by 304, we get 9 and a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 179026.19
Subtract 2736 from 2960 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
When dividing 2240 by 304, we get 7 with a remainder of 112.
The next digit of our result is 7. 
Result so far: 179026.197
If we take 2128 away from 2240, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
304 goes into 1120 3 times with a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 179026.1973
Subtracting 912 from 1120 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 13:
The number 304 fits into 2080 6 times, leaving a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 179026.19736
The remainder is 256 after subtracting 1824 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
304 can be fit into 2560 8 times, resulting in a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 179026.197368
If we take 2432 away from 2560, we end up with 128.
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 15:
304 can be fit into 1280 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 179026.1973684
Subtract 1216 from 1280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
304 goes into 640 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 179026.19736842
Subtracting 608 from 640 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 179026.19736842 with a remainder of 3.2e-08.
