Let's divide 86346581 by 304
The aim is to understand the frequency of 304 in 86346581.

Advancing to step 1:
8 divided by 304 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 304

Advancing to step 2:
If we divide 86 by 304, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 304

Moving on to step 3:
863 divided by 304 is 2 with a remainder of 255.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 608 from 863 and we're left with 255.
Append the next digit (4) from the dividend to 255 and continue with: 2554 / 304

Advancing to step 4:
304 can be fit into 2554 8 times, resulting in a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 2432 from 2554 and we're left with 122.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 304

Moving on to step 5:
304 goes into 1226 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 284.0
If we take 1216 away from 1226, we end up with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 304

On to step 6:
304 can be fit into 105 0 times, resulting in a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 2840.0
Subtract 0 from 105 to get 105.
Grab the next digit (8) from the dividend, add it to 105, then carry on: 1058 / 304

On to step 7:
1058 divided by 304 is 3 with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 28403.0
If we take 912 away from 1058, we end up with 146.
Include the next digit (1) from the dividend after 146, then repeat: 1461 / 304

Moving on to step 8:
1461 divided by 304 is 4 with a remainder of 245.
The next digit of our result is 4. 
Result so far: 284034.0
Subtracting 1216 from 1461 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 9:
304 goes into 2450 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 284034.8
If we subtract 2432 from 2450, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
304 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 284034.8
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
The number 304 fits into 1800 5 times, leaving a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 284034.805
The remainder is 280 after subtracting 1520 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
304 can be fit into 2800 9 times, resulting in a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 284034.8059
Subtract 2736 from 2800 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.

Advancing to step 13:
When dividing 640 by 304, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 284034.80592
Subtract 608 from 640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
304 goes into 320 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 284034.805921
If we subtract 304 from 320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
160 divided by 304 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 284034.805921
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
304 goes into 1600 5 times with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 284034.80592105
The remainder is 80 after subtracting 1520 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 284034.80592105, and the remainder is 8e-08.
