31684030 divided by 308 
The aim is to understand the frequency of 308 in 31684030.

Moving on to step 1:
308 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 308

Moving on to step 2:
308 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 308

Advancing to step 3:
316 divided by 308 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 308 from 316 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 308

Moving on to step 4:
The number 308 fits into 88 0 times, leaving a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 88 to get 88.
Bring next digit (4) of the dividend behind the 88 and repeat the process: 884 / 308

Moving on to step 5:
308 can be fit into 884 2 times, resulting in a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
The remainder is 268 after subtracting 616 from 884.
Grab the next digit (0) from the dividend, add it to 268, then carry on: 2680 / 308

Let's proceed to step 6:
308 can be fit into 2680 8 times, resulting in a remainder of 216.
The next digit of our result is 8. 
Result so far: 1028.0
If we take 2464 away from 2680, we end up with 216.
Append the next digit (3) from the dividend to 216 and continue with: 2163 / 308

Going ahead to step 7:
308 can be fit into 2163 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 10287.0
If we take 2156 away from 2163, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 308

Let's proceed to step 8:
When dividing 70 by 308, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 102870.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
700 divided by 308 is 2 with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 102870.2
Deduct 616 from 700 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
If we divide 840 by 308, we get 2 and a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 102870.22
Deduct 616 from 840 and we're left 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.

In conclusion, the division gives 102870.22 with a balance of 0.224.
