917371 divided by 30 
The aim is to understand the frequency of 30 in 917371.

On to step 1:
When dividing 9 by 30, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 30

On to step 2:
30 goes into 91 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 90 from 91.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 30

Going ahead to step 3:
When dividing 17 by 30, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 17 to get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 30

Advancing 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: 305.0
Subtract 150 from 173 to get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 30

Moving on to step 5:
When dividing 237 by 30, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3057.0
Deduct 210 from 237 and we're left with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 30

Going ahead to step 6:
271 divided by 30 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 30579.0
If we subtract 270 from 271, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 30579.0
The remainder is 10 after subtracting 0 from 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 8:
100 divided by 30 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 30579.03
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 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 30579.033
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 30579.033 with a balance of 0.001.
