We look at the division of 179400 by 30 
The aim is to understand the frequency of 30 in 179400.

Going ahead to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 30

Step 2:
When dividing 17 by 30, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 30

Step 3:
The number 30 fits into 179 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 150 from 179, we get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 30

On to step 4:
30 goes into 294 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we take 270 away from 294, we end up with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 30

Let's proceed to step 5:
If we divide 240 by 30, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 598.0
If we subtract 240 from 240, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 30

Step 6:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5980.0
Subtracting 0 from 0 leaves us 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.

On to step 7:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5980.0
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.

Step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5980.0
If we subtract 0 from 0, 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.

The final result is 5980.0 with a remainder of 0.0.
