We're dividing 881519 by 30 
The aim is to understand the frequency of 30 in 881519.

Let's proceed to 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
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 30

Moving on to step 2:
30 goes into 88 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 28 after subtracting 60 from 88.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 30

Step 3:
30 goes into 281 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 270 from 281 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 30

Let's proceed to step 4:
30 can be fit into 115 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 25 after subtracting 90 from 115.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 30

Let's proceed to step 5:
When dividing 251 by 30, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 2938.0
If we subtract 240 from 251, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 30

On to step 6:
If we divide 119 by 30, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 29383.0
If we take 90 away from 119, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 29383.9
If we subtract 270 from 290, 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:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 29383.96
The remainder is 20 after subtracting 180 from 200.
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 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 29383.966
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.

The final outcome is 29383.966, with a leftover of 0.002.
