We divide 28483209 by 393
The aim is to understand the frequency of 393 in 28483209.

On to step 1:
393 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 393

Moving on to step 2:
393 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 393

Let's proceed to step 3:
The number 393 fits into 284 0 times, leaving a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 284 and we're left with 284.
Append the next digit (8) from the dividend to 284 and continue with: 2848 / 393

Moving on to step 4:
The number 393 fits into 2848 7 times, leaving a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 97 after subtracting 2751 from 2848.
Include the next digit (3) from the dividend after 97, then repeat: 973 / 393

Moving on to step 5:
393 can be fit into 973 2 times, resulting in a remainder of 187.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtracting 786 from 973 leaves us with 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 393

Going ahead to step 6:
If we divide 1872 by 393, we get 4 and a remainder of 300.
Write down 4 as next digit of the result. 
Result so far: 724.0
If we subtract 1572 from 1872, we get 300.
Include the next digit (0) from the dividend after 300, then repeat: 3000 / 393

Going ahead to step 7:
393 can be fit into 3000 7 times, resulting in a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 7247.0
Deduct 2751 from 3000 and we're left with 249.
Include the next digit (9) from the dividend after 249, then repeat: 2499 / 393

On to step 8:
393 goes into 2499 6 times with a remainder of 141.
The number 6 becomes the next digit in our result. 
Result so far: 72476.0
Subtract 2358 from 2499 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
1410 divided by 393 is 3 with a remainder of 231.
Put 3 as the next digit of the answer. 
Result so far: 72476.3
Subtract 1179 from 1410 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 10:
If we divide 2310 by 393, we get 5 and a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 72476.35
Deduct 1965 from 2310 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 11:
If we divide 3450 by 393, we get 8 and a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 72476.358
If we take 3144 away from 3450, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 12:
When dividing 3060 by 393, we get 7 with a remainder of 309.
The next digit of our result is 7. 
Result so far: 72476.3587
Subtract 2751 from 3060 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 13:
If we divide 3090 by 393, we get 7 and a remainder of 339.
Use 7 as the next digit of our solution. 
Result so far: 72476.35877
Subtract 2751 from 3090 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

In conclusion, the division gives 72476.35877 with a balance of 0.000339.
