We divide 154646 by 30
The aim is to understand the frequency of 30 in 154646.

Let's proceed to step 1:
1 divided by 30 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 30

Going ahead to step 2:
When dividing 15 by 30, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 30

Step 3:
154 divided by 30 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 150 from 154 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 30

Going ahead to step 4:
30 can be fit into 46 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 30 from 46, we get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 30

On to step 5:
30 can be fit into 164 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 515.0
Subtract 150 from 164 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 30

Moving on to step 6:
The number 30 fits into 146 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 5154.0
If we take 120 away from 146, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
The number 30 fits into 260 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 5154.8
The remainder is 20 after subtracting 240 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 5154.86
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5154.866
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 5154.866, with a leftover of 0.002.
