Let's divide 494500 by 30
The aim is to understand the frequency of 30 in 494500.

Advancing to step 1:
4 divided by 30 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 30

On to step 2:
The number 30 fits into 49 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 49 to get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 30

Going ahead to step 3:
The number 30 fits into 194 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 180 from 194, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 30

Going ahead to step 4:
When dividing 145 by 30, we get 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
If we take 120 away from 145, we end up with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 30

Moving on to step 5:
30 can be fit into 250 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1648.0
Subtracting 240 from 250 leaves us with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 30

Moving on to step 6:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 16483.0
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 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 16483.3
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.

Going ahead 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: 16483.33
Subtracting 90 from 100 leaves us 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.

The quotient of the division is 16483.33, and the remainder is 0.01.
