Let's divide 4429583 by 304
The aim is to understand the frequency of 304 in 4429583.

Going ahead to step 1:
304 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 304

Step 2:
The number 304 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 304

On to step 3:
If we divide 442 by 304, we get 1 and a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 304 from 442 to get 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 304

Moving on to step 4:
304 can be fit into 1389 4 times, resulting in a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1216 away from 1389, we end up with 173.
Grab the next digit (5) from the dividend, add it to 173, then carry on: 1735 / 304

Going ahead to step 5:
When dividing 1735 by 304, we get 5 with a remainder of 215.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 1520 from 1735 leaves us with 215.
Take the next digit (8) from the dividend and append it to 215, then repeat: 2158 / 304

Let's proceed to step 6:
2158 divided by 304 is 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 1457.0
Subtracting 2128 from 2158 leaves us with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 304

Going ahead to step 7:
When dividing 303 by 304, we get 0 with a remainder of 303.
The next digit of our result is 0. 
Result so far: 14570.0
Subtracting 0 from 303 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 8:
304 can be fit into 3030 9 times, resulting in a remainder of 294.
Use 9 as the next digit of our solution. 
Result so far: 14570.9
If we take 2736 away from 3030, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
304 can be fit into 2940 9 times, resulting in a remainder of 204.
Write down 9 as next digit of the result. 
Result so far: 14570.99
Subtract 2736 from 2940 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Our division results in 14570.99 with a remaining 0.204.
