We look at the division of 830300 by 25 
The aim is to understand the frequency of 25 in 830300.

Moving on to step 1:
8 divided by 25 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 25

Moving on to step 2:
The number 25 fits into 83 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 75 from 83, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 25

Moving on to step 3:
25 can be fit into 80 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 75 from 80 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 25

Going ahead to step 4:
25 can be fit into 53 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 332.0
Deduct 50 from 53 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 25

Moving on to step 5:
The number 25 fits into 30 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3321.0
If we subtract 25 from 30, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 25

Going ahead to step 6:
50 divided by 25 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 33212.0
The remainder is 0 after subtracting 50 from 50.
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 7:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33212.0
Subtract 0 from 0 to 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.

Advancing to step 8:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33212.0
Subtract 0 from 0 to 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.

The quotient of the division is 33212.0, and the remainder is 0.0.
