63479228 ÷ 509 
The aim is to understand the frequency of 509 in 63479228.

Going ahead to step 1:
The number 509 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 509

Step 2:
When dividing 63 by 509, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 509

Going ahead to step 3:
509 can be fit into 634 1 times, resulting in a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 509 away from 634, we end up with 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 509

Step 4:
The number 509 fits into 1257 2 times, leaving a remainder of 239.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1018 from 1257 to get 239.
Take the next digit (9) from the dividend and append it to 239, then repeat: 2399 / 509

Step 5:
509 goes into 2399 4 times with a remainder of 363.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 2036 away from 2399, we end up with 363.
Fetch the next digit (2) from the dividend, attach it to 363 and continue: 3632 / 509

Advancing to step 6:
If we divide 3632 by 509, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 1247.0
Subtract 3563 from 3632 to get 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 509

Step 7:
509 can be fit into 692 1 times, resulting in a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 12471.0
If we take 509 away from 692, we end up with 183.
Append the next digit (8) from the dividend to 183 and continue with: 1838 / 509

Step 8:
509 goes into 1838 3 times with a remainder of 311.
The next digit of our result is 3. 
Result so far: 124713.0
Deduct 1527 from 1838 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 9:
If we divide 3110 by 509, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 124713.6
The remainder is 56 after subtracting 3054 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
560 divided by 509 is 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 124713.61
Deduct 509 from 560 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
If we divide 510 by 509, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 124713.611
Subtract 509 from 510 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 124713.611, with a leftover of 0.0001.
