Let's divide 28001982 by 576
The aim is to understand the frequency of 576 in 28001982.

Step 1:
If we divide 2 by 576, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 576

Advancing to step 2:
576 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 576

Moving on to step 3:
The number 576 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 280 and we're left with 280.
Bring next digit (0) of the dividend behind the 280 and repeat the process: 2800 / 576

Advancing to step 4:
576 goes into 2800 4 times with a remainder of 496.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2304 from 2800 to get 496.
Grab the next digit (1) from the dividend, add it to 496, then carry on: 4961 / 576

Advancing to step 5:
The number 576 fits into 4961 8 times, leaving a remainder of 353.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 353 after subtracting 4608 from 4961.
Grab the next digit (9) from the dividend, add it to 353, then carry on: 3539 / 576

Step 6:
576 goes into 3539 6 times with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 486.0
If we take 3456 away from 3539, we end up with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 576

On to step 7:
576 goes into 838 1 times with a remainder of 262.
The next digit of our result is 1. 
Result so far: 4861.0
Deduct 576 from 838 and we're left with 262.
Grab the next digit (2) from the dividend, add it to 262, then carry on: 2622 / 576

Let's proceed to step 8:
If we divide 2622 by 576, we get 4 and a remainder of 318.
The next digit of our result is 4. 
Result so far: 48614.0
Deduct 2304 from 2622 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 9:
The number 576 fits into 3180 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 48614.5
If we take 2880 away from 3180, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
3000 divided by 576 is 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 48614.55
If we take 2880 away from 3000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 48614.55 and a remainder of 0.12.
