We divide 228886 by 30
The aim is to understand the frequency of 30 in 228886.

Step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 30

Moving on to step 2:
When dividing 22 by 30, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 30

Let's proceed to step 3:
30 can be fit into 228 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 210 from 228 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 30

Advancing to step 4:
If we divide 188 by 30, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 180 from 188 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 30

Moving on to step 5:
If we divide 88 by 30, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 762.0
Deduct 60 from 88 and we're left with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 30

On to step 6:
286 divided by 30 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 7629.0
Subtract 270 from 286 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
30 can be fit into 160 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7629.5
The remainder is 10 after subtracting 150 from 160.
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:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7629.53
If we subtract 90 from 100, we 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.

On to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7629.533
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 result is 7629.533 with a remainder of 0.001.
