We look at the division of 63715571 by 304 
The aim is to understand the frequency of 304 in 63715571.

Moving on to step 1:
If we divide 6 by 304, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 304

On to step 2:
If we divide 63 by 304, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 304

Step 3:
The number 304 fits into 637 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 29 after subtracting 608 from 637.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 304

Going ahead to step 4:
304 goes into 291 0 times with a remainder of 291.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 291 to get 291.
Append the next digit (5) from the dividend to 291 and continue with: 2915 / 304

Going ahead to step 5:
When dividing 2915 by 304, we get 9 with a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 209.0
If we take 2736 away from 2915, we end up with 179.
Include the next digit (5) from the dividend after 179, then repeat: 1795 / 304

Let's proceed to step 6:
1795 divided by 304 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 2095.0
Subtracting 1520 from 1795 leaves us with 275.
Take the next digit (7) from the dividend and append it to 275, then repeat: 2757 / 304

Let's proceed to step 7:
When dividing 2757 by 304, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 20959.0
If we take 2736 away from 2757, we end up with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 304

On to step 8:
If we divide 211 by 304, we get 0 and a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 209590.0
Subtract 0 from 211 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 9:
304 can be fit into 2110 6 times, resulting in a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 209590.6
Subtracting 1824 from 2110 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
When dividing 2860 by 304, we get 9 with a remainder of 124.
Write down 9 as next digit of the result. 
Result so far: 209590.69
Deduct 2736 from 2860 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 11:
The number 304 fits into 1240 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 209590.694
Subtract 1216 from 1240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
304 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 209590.694
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
When dividing 2400 by 304, we get 7 with a remainder of 272.
The next digit of our result is 7. 
Result so far: 209590.69407
If we take 2128 away from 2400, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 14:
The number 304 fits into 2720 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 209590.694078
If we subtract 2432 from 2720, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
304 goes into 2880 9 times with a remainder of 144.
Use 9 as the next digit of our solution. 
Result so far: 209590.6940789
The remainder is 144 after subtracting 2736 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 16:
304 can be fit into 1440 4 times, resulting in a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 209590.69407894
If we take 1216 away from 1440, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

After the division, we end up with 209590.69407894 and a remainder of 2.24e-07.
