350655 divided by 30 
The aim is to understand the frequency of 30 in 350655.

Let's proceed to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 30

Advancing to step 2:
35 divided by 30 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 30 from 35 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 30

On to step 3:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 30 from 50 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 30

Step 4:
If we divide 206 by 30, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 180 from 206 to get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 30

Advancing to step 5:
30 can be fit into 265 8 times, resulting in a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 1168.0
Subtracting 240 from 265 leaves us with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 30

Advancing to step 6:
30 can be fit into 255 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 11688.0
If we take 240 away from 255, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 30, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11688.5
Subtracting 150 from 150 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11688.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11688.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11688.5, with a leftover of 0.0.
