971386 divided by 30 
The aim is to understand the frequency of 30 in 971386.

Going ahead to step 1:
9 divided by 30 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 30

Step 2:
30 goes into 97 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 90 away from 97, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 30

On to step 3:
The number 30 fits into 71 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 60 away from 71, we end up with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 30

Going ahead to step 4:
If we divide 113 by 30, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
If we take 90 away from 113, we end up with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 30

Let's proceed to step 5:
238 divided by 30 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 3237.0
Subtract 210 from 238 to get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 30

Let's proceed to step 6:
The number 30 fits into 286 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 32379.0
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.

Advancing to step 7:
If we divide 160 by 30, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 32379.5
Subtracting 150 from 160 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 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 32379.53
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:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 32379.533
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.

In conclusion, the division gives 32379.533 with a balance of 0.001.
