We look at the division of 30665223 by 849 
The aim is to understand the frequency of 849 in 30665223.

Advancing to step 1:
The number 849 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 849

Step 2:
30 divided by 849 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 849

Moving on to step 3:
If we divide 306 by 849, we get 0 and a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 306 to get 306.
Grab the next digit (6) from the dividend, add it to 306, then carry on: 3066 / 849

Let's proceed to step 4:
849 can be fit into 3066 3 times, resulting in a remainder of 519.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2547 from 3066, we get 519.
Take the next digit (5) from the dividend and append it to 519, then repeat: 5195 / 849

Advancing to step 5:
5195 divided by 849 is 6 with a remainder of 101.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 5094 from 5195 to get 101.
Grab the next digit (2) from the dividend, add it to 101, then carry on: 1012 / 849

Moving on to step 6:
849 can be fit into 1012 1 times, resulting in a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 361.0
If we subtract 849 from 1012, we get 163.
Include the next digit (2) from the dividend after 163, then repeat: 1632 / 849

On to step 7:
849 goes into 1632 1 times with a remainder of 783.
Write down 1 as next digit of the result. 
Result so far: 3611.0
Subtract 849 from 1632 to get 783.
Include the next digit (3) from the dividend after 783, then repeat: 7833 / 849

Advancing to step 8:
When dividing 7833 by 849, we get 9 with a remainder of 192.
Record the quotient 9 as the next digit in the result. 
Result so far: 36119.0
Subtract 7641 from 7833 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 9:
1920 divided by 849 is 2 with a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 36119.2
Deduct 1698 from 1920 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 10:
849 goes into 2220 2 times with a remainder of 522.
Record the quotient 2 as the next digit in the result. 
Result so far: 36119.22
Subtract 1698 from 2220 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

In conclusion, the division gives 36119.22 with a balance of 0.522.
