We divide 387922 by 30
The aim is to understand the frequency of 30 in 387922.

Moving on to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 30

Let's proceed to step 2:
30 goes into 38 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 38, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 30

On to step 3:
30 can be fit into 87 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 60 from 87 and we're left with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 30

Advancing to step 4:
30 can be fit into 279 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtracting 270 from 279 leaves us with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 30

On to step 5:
30 can be fit into 92 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 1293.0
The remainder is 2 after subtracting 90 from 92.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 30

Step 6:
The number 30 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 12930.0
Deduct 0 from 22 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.

On to step 7:
30 can be fit into 220 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 12930.7
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.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 12930.73
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.

Advancing to step 9:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 12930.733
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.

Our division results in 12930.733 with a remaining 0.001.
