We're dividing 154201 by 30 
The aim is to understand the frequency of 30 in 154201.

Moving on to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 30

Advancing to step 2:
30 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 30

Moving on to step 3:
154 divided by 30 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 150 away from 154, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 30

Going ahead to step 4:
The number 30 fits into 42 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 30 from 42, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 30

On to step 5:
30 goes into 120 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 514.0
If we subtract 120 from 120, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 30

Advancing to step 6:
30 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 5140.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5140.0
Deduct 0 from 10 and we're left 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.

Advancing to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 5140.03
If we take 90 away from 100, we end up 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.

Step 9:
30 goes into 100 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 5140.033
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 5140.033 with a remainder of 0.001.
