742100 divided by 30 
The aim is to understand the frequency of 30 in 742100.

Moving on to step 1:
30 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 30

Going ahead to step 2:
If we divide 74 by 30, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 74 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 30

Going ahead to step 3:
30 can be fit into 142 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 120 away from 142, we end up with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 30

Let's proceed to step 4:
30 can be fit into 221 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 247.0
Subtract 210 from 221 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 30

Moving on to step 5:
30 can be fit into 110 3 times, resulting in a remainder of 20.
The next digit of our result is 3. 
Result so far: 2473.0
If we subtract 90 from 110, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 30

On to step 6:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 24736.0
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 24736.6
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 24736.66
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 24736.66 with a balance of 0.02.
