We divide 19290388 by 30
The aim is to understand the frequency of 30 in 19290388.

Moving on to step 1:
1 divided by 30 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 30

Advancing to step 2:
19 divided by 30 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 30

Step 3:
The number 30 fits into 192 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 180 from 192 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 30

Going ahead to step 4:
If we divide 129 by 30, we get 4 and a remainder of 9.
The next digit of our result is 4. 
Result so far: 64.0
If we take 120 away from 129, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 30

Going ahead to step 5:
The number 30 fits into 90 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 643.0
Deduct 90 from 90 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 30

On to step 6:
When dividing 3 by 30, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 6430.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 30

Step 7:
When dividing 38 by 30, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 64301.0
If we take 30 away from 38, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 30

Let's proceed to step 8:
30 can be fit into 88 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 643012.0
Deduct 60 from 88 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 30 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 643012.9
If we subtract 270 from 280, we get 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 10:
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: 643012.93
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 643012.933
Subtracting 90 from 100 leaves us 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.

The quotient of the division is 643012.933, and the remainder is 0.001.
