616633 divided by 30 
The aim is to understand the frequency of 30 in 616633.

Let's proceed to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 30

Let's proceed to step 2:
61 divided by 30 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 60 from 61 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 30

Moving on to step 3:
The number 30 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 16 to get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 30

On to step 4:
30 can be fit into 166 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtracting 150 from 166 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 30

Advancing to step 5:
If we divide 163 by 30, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 2055.0
Subtract 150 from 163 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 30

Moving on to step 6:
30 goes into 133 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 20554.0
Subtracting 120 from 133 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 30 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 20554.4
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 20554.43
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 20554.433
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 20554.433 with a remaining 0.001.
