We divide 104791 by 30
The aim is to understand the frequency of 30 in 104791.

Advancing to step 1:
1 divided by 30 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 30

Going ahead to step 2:
If we divide 10 by 30, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 30

Advancing to step 3:
When dividing 104 by 30, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 90 from 104, we get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 30

Advancing to step 4:
The number 30 fits into 147 4 times, leaving a remainder of 27.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 120 from 147, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 30

On to step 5:
30 can be fit into 279 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 349.0
If we take 270 away from 279, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 30

Moving on to step 6:
The number 30 fits into 91 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3493.0
Deduct 90 from 91 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3493.0
If we subtract 0 from 10, we 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.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3493.03
If we take 90 away from 100, 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 9:
30 goes into 100 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3493.033
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.

After the division, we end up with 3493.033 and a remainder of 0.001.
