We're dividing 162030 by 3 
The aim is to understand the frequency of 3 in 162030.

Going ahead to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Advancing to step 2:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 15 away from 16, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Moving on to step 3:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 12 from 12 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

On to step 4:
If we divide 0 by 3, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.0
If we take 0 away from 0, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Going ahead to step 5:
3 divided by 3 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 5401.0
Deduct 3 from 3 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Advancing to step 6:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54010.0
Deduct 0 from 0 and we're left 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.

Advancing to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54010.0
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.

On to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54010.0
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 54010.0 with a balance of 0.0.
