905238 divided by 30 
The aim is to understand the frequency of 30 in 905238.

Going ahead to step 1:
The number 30 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 30

On to step 2:
The number 30 fits into 90 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 0 after subtracting 90 from 90.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 30

Let's proceed to step 3:
When dividing 5 by 30, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 30

On to step 4:
When dividing 52 by 30, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 301.0
If we subtract 30 from 52, we get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 30

Going ahead to step 5:
If we divide 223 by 30, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 3017.0
Subtract 210 from 223 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 30

Moving on to step 6:
When dividing 138 by 30, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 30174.0
If we subtract 120 from 138, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 30, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 30174.6
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30174.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 30174.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 30174.6, and the remainder is 0.0.
