353867 divided by 30 
The aim is to understand the frequency of 30 in 353867.

Moving on to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 30

Going ahead to step 2:
When dividing 35 by 30, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 30 away from 35, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 30

Going ahead to step 3:
The number 30 fits into 53 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 30 from 53 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 30

Advancing to step 4:
238 divided by 30 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 210 away from 238, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 30

Moving on to step 5:
The number 30 fits into 286 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 1179.0
If we take 270 away from 286, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 30

Let's proceed to step 6:
30 can be fit into 167 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 11795.0
If we subtract 150 from 167, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
30 can be fit into 170 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 11795.5
If we subtract 150 from 170, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 11795.56
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 11795.566
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 11795.566 and a remainder of 0.002.
