801723 divided by 30 
The aim is to understand the frequency of 30 in 801723.

Moving on to step 1:
30 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 30

Moving on to step 2:
The number 30 fits into 80 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 80, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 30

Step 3:
The number 30 fits into 201 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 180 from 201, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 30

Moving on to step 4:
If we divide 217 by 30, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 267.0
Deduct 210 from 217 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 30

On to step 5:
If we divide 72 by 30, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2672.0
Subtracting 60 from 72 leaves us with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 30

Going ahead to step 6:
30 can be fit into 123 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 26724.0
If we subtract 120 from 123, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 can be fit into 30 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 26724.1
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26724.1
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.

Step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26724.1
Subtracting 0 from 0 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.

After the division, we end up with 26724.1 and a remainder of 0.0.
