We divide 871030 by 30
The aim is to understand the frequency of 30 in 871030.

Step 1:
If we divide 8 by 30, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 30

On to step 2:
30 goes into 87 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 27 after subtracting 60 from 87.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 30

On to step 3:
If we divide 271 by 30, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 270 away from 271, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 30

Step 4:
When dividing 10 by 30, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 290.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 30

On to step 5:
When dividing 103 by 30, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2903.0
Subtracting 90 from 103 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 30

Going ahead to step 6:
When dividing 130 by 30, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 29034.0
Subtracting 120 from 130 leaves us 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 7:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 29034.3
If we take 90 away from 100, 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:
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: 29034.33
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.

In conclusion, the division gives 29034.33 with a balance of 0.01.
