We're dividing 47499033 by 509 
The aim is to understand the frequency of 509 in 47499033.

On to step 1:
When dividing 4 by 509, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 509

Moving on to step 2:
The number 509 fits into 47 0 times, leaving a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 509

Step 3:
474 divided by 509 is 0 with a remainder of 474.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 474 after subtracting 0 from 474.
Include the next digit (9) from the dividend after 474, then repeat: 4749 / 509

Step 4:
If we divide 4749 by 509, we get 9 and a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 168 after subtracting 4581 from 4749.
Bring next digit (9) of the dividend behind the 168 and repeat the process: 1689 / 509

Moving on to step 5:
1689 divided by 509 is 3 with a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 1527 from 1689 to get 162.
Fetch the next digit (0) from the dividend, attach it to 162 and continue: 1620 / 509

Moving on to step 6:
If we divide 1620 by 509, we get 3 and a remainder of 93.
The next digit of our result is 3. 
Result so far: 933.0
The remainder is 93 after subtracting 1527 from 1620.
Grab the next digit (3) from the dividend, add it to 93, then carry on: 933 / 509

Step 7:
If we divide 933 by 509, we get 1 and a remainder of 424.
The number 1 becomes the next digit in our result. 
Result so far: 9331.0
Subtracting 509 from 933 leaves us with 424.
Bring next digit (3) of the dividend behind the 424 and repeat the process: 4243 / 509

Going ahead to step 8:
4243 divided by 509 is 8 with a remainder of 171.
Put 8 as the next digit of the answer. 
Result so far: 93318.0
Subtract 4072 from 4243 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
509 goes into 1710 3 times with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 93318.3
If we take 1527 away from 1710, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 10:
509 goes into 1830 3 times with a remainder of 303.
Record the quotient 3 as the next digit in the result. 
Result so far: 93318.33
If we take 1527 away from 1830, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final result is 93318.33 with a remainder of 0.303.
