182020 ÷ 30 
The aim is to understand the frequency of 30 in 182020.

Advancing to step 1:
30 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 30

Going ahead to step 2:
The number 30 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 30

Advancing to step 3:
When dividing 182 by 30, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 180 from 182 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 30

On to step 4:
When dividing 20 by 30, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 20 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 30

Step 5:
The number 30 fits into 202 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 606.0
Subtracting 180 from 202 leaves us with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 30

On to step 6:
30 goes into 220 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 6067.0
If we take 210 away from 220, 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.

Advancing to step 7:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 6067.3
Deduct 90 from 100 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.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 6067.33
Subtract 90 from 100 to get 10.
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 outcome is 6067.33, with a leftover of 0.01.
