We're dividing 566812 by 30 
The aim is to understand the frequency of 30 in 566812.

Advancing to step 1:
30 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 30

Let's proceed to step 2:
If we divide 56 by 30, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 56 to get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 30

Moving on to step 3:
When dividing 266 by 30, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 240 from 266 leaves us with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 30

On to step 4:
30 can be fit into 268 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 188.0
If we subtract 240 from 268, we get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 30

Step 5:
30 can be fit into 281 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 1889.0
If we subtract 270 from 281, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 30

Going ahead to step 6:
The number 30 fits into 112 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 18893.0
Deduct 90 from 112 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
30 goes into 220 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 18893.7
Subtracting 210 from 220 leaves us 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.

Going ahead to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 18893.73
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.

Moving on to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 18893.733
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.

Our division results in 18893.733 with a remaining 0.001.
