We're dividing 267517 by 30 
The aim is to understand the frequency of 30 in 267517.

On to step 1:
2 divided by 30 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 30

On to step 2:
30 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 30

Step 3:
30 goes into 267 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 240 from 267 to get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 30

Advancing to step 4:
When dividing 275 by 30, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 270 away from 275, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 30

Advancing to step 5:
When dividing 51 by 30, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 891.0
If we take 30 away from 51, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 30

Step 6:
If we divide 217 by 30, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 8917.0
If we take 210 away from 217, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 30, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 8917.2
If we take 60 away from 70, 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.

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: 8917.23
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.

Moving on to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 8917.233
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.

After the division, we end up with 8917.233 and a remainder of 0.001.
