73143239 ÷ 304 
The aim is to understand the frequency of 304 in 73143239.

Step 1:
304 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 304

On to step 2:
73 divided by 304 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 304

On to step 3:
304 can be fit into 731 2 times, resulting in a remainder of 123.
The next digit of our result is 2. 
Result so far: 2.0
If we take 608 away from 731, we end up with 123.
Append the next digit (4) from the dividend to 123 and continue with: 1234 / 304

Let's proceed to step 4:
The number 304 fits into 1234 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 18 after subtracting 1216 from 1234.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 304

Advancing to step 5:
304 goes into 183 0 times with a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 240.0
If we take 0 away from 183, we end up with 183.
Include the next digit (2) from the dividend after 183, then repeat: 1832 / 304

Let's proceed to step 6:
The number 304 fits into 1832 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2406.0
Subtracting 1824 from 1832 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 304

On to step 7:
When dividing 83 by 304, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 24060.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 304

Let's proceed to step 8:
304 goes into 839 2 times with a remainder of 231.
The next digit of our result is 2. 
Result so far: 240602.0
Deduct 608 from 839 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 9:
When dividing 2310 by 304, we get 7 with a remainder of 182.
Put 7 as the next digit of the answer. 
Result so far: 240602.7
Subtract 2128 from 2310 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
1820 divided by 304 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 240602.75
If we subtract 1520 from 1820, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
304 can be fit into 3000 9 times, resulting in a remainder of 264.
The number 9 becomes the next digit in our result. 
Result so far: 240602.759
If we subtract 2736 from 3000, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
304 can be fit into 2640 8 times, resulting in a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 240602.7598
If we take 2432 away from 2640, we end up 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.

Let's proceed to step 13:
When dividing 2080 by 304, we get 6 with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 240602.75986
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.

Moving on to step 14:
2560 divided by 304 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 240602.759868
If we subtract 2432 from 2560, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
304 goes into 1280 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 240602.7598684
Subtracting 1216 from 1280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
640 divided by 304 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 240602.75986842
Deduct 608 from 640 and we're left 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.

Our division results in 240602.75986842 with a remaining 3.2e-08.
