Let's divide 887345 by 30
The aim is to understand the frequency of 30 in 887345.

Step 1:
If we divide 8 by 30, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 30

Moving on to step 2:
When dividing 88 by 30, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 88 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 30

Moving on to step 3:
30 can be fit into 287 9 times, resulting in a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 270 from 287, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 30

Moving on to step 4:
30 can be fit into 173 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 295.0
Deduct 150 from 173 and we're left with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 30

Step 5:
The number 30 fits into 234 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 2957.0
If we take 210 away from 234, we end up with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 30

Moving on to step 6:
The number 30 fits into 245 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 29578.0
Subtract 240 from 245 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
30 goes into 50 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 29578.1
If we subtract 30 from 50, 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.

Advancing to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 29578.16
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.

Step 9:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 29578.166
Subtract 180 from 200 to 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.

The final result is 29578.166 with a remainder of 0.002.
