We divide 317263 by 30
The aim is to understand the frequency of 30 in 317263.

Let's proceed to step 1:
30 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

Step 2:
The number 30 fits into 31 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 31, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 30

Moving on to step 3:
30 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 30

Advancing to step 4:
30 goes into 172 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 150 from 172 leaves us with 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 30

Moving on to step 5:
226 divided by 30 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 1057.0
Subtracting 210 from 226 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 30

Step 6:
If we divide 163 by 30, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 10575.0
Subtract 150 from 163 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
30 can be fit into 130 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 10575.4
Deduct 120 from 130 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.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 10575.43
Subtracting 90 from 100 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.

Advancing to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 10575.433
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10575.433, with a leftover of 0.001.
