30391780 divided by 984 
The aim is to understand the frequency of 984 in 30391780.

On to step 1:
984 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 984

Let's proceed to step 2:
30 divided by 984 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 984

Step 3:
984 goes into 303 0 times with a remainder of 303.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 303 to get 303.
Append the next digit (9) from the dividend to 303 and continue with: 3039 / 984

Step 4:
If we divide 3039 by 984, we get 3 and a remainder of 87.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 87 after subtracting 2952 from 3039.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 984

On to step 5:
984 goes into 871 0 times with a remainder of 871.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 871, we end up with 871.
Bring next digit (7) of the dividend behind the 871 and repeat the process: 8717 / 984

Going ahead to step 6:
8717 divided by 984 is 8 with a remainder of 845.
Use 8 as the next digit of our solution. 
Result so far: 308.0
Subtract 7872 from 8717 to get 845.
Fetch the next digit (8) from the dividend, attach it to 845 and continue: 8458 / 984

Step 7:
984 goes into 8458 8 times with a remainder of 586.
Record the quotient 8 as the next digit in the result. 
Result so far: 3088.0
Deduct 7872 from 8458 and we're left with 586.
Append the next digit (0) from the dividend to 586 and continue with: 5860 / 984

Going ahead to step 8:
5860 divided by 984 is 5 with a remainder of 940.
Put 5 as the next digit of the answer. 
Result so far: 30885.0
Deduct 4920 from 5860 and we're left with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 9:
When dividing 9400 by 984, we get 9 with a remainder of 544.
Put 9 as the next digit of the answer. 
Result so far: 30885.9
If we subtract 8856 from 9400, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 10:
984 can be fit into 5440 5 times, resulting in a remainder of 520.
Write down 5 as next digit of the result. 
Result so far: 30885.95
Subtracting 4920 from 5440 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
984 can be fit into 5200 5 times, resulting in a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 30885.955
Subtract 4920 from 5200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 30885.955, with a leftover of 0.028.
