We divide 58727 by 30
The aim is to understand the frequency of 30 in 58727.

On to step 1:
5 divided by 30 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 30

Going ahead to step 2:
58 divided by 30 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 58, we get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 30

Going ahead to step 3:
287 divided by 30 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 270 from 287 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 30

Moving on to step 4:
30 can be fit into 172 5 times, resulting in a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Deduct 150 from 172 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 30

Moving on to step 5:
If we divide 227 by 30, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 1957.0
Deduct 210 from 227 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 6:
If we divide 170 by 30, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1957.5
If we subtract 150 from 170, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 1957.56
If we subtract 180 from 200, we get 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 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1957.566
If we take 180 away from 200, we end up 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 result is 1957.566 with a remainder of 0.002.
