We look at the division of 28099249 by 784 
The aim is to understand the frequency of 784 in 28099249.

Let's proceed to step 1:
When dividing 2 by 784, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 784

Step 2:
28 divided by 784 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 784

On to step 3:
If we divide 280 by 784, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 280, we get 280.
Bring next digit (9) of the dividend behind the 280 and repeat the process: 2809 / 784

Advancing to step 4:
If we divide 2809 by 784, we get 3 and a remainder of 457.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 457 after subtracting 2352 from 2809.
Append the next digit (9) from the dividend to 457 and continue with: 4579 / 784

Step 5:
784 can be fit into 4579 5 times, resulting in a remainder of 659.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 3920 from 4579 to get 659.
Take the next digit (2) from the dividend and append it to 659, then repeat: 6592 / 784

Advancing to step 6:
When dividing 6592 by 784, we get 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 358.0
The remainder is 320 after subtracting 6272 from 6592.
Fetch the next digit (4) from the dividend, attach it to 320 and continue: 3204 / 784

Advancing to step 7:
If we divide 3204 by 784, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 3584.0
If we subtract 3136 from 3204, we get 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 784

Moving on to step 8:
784 can be fit into 689 0 times, resulting in a remainder of 689.
The number 0 becomes the next digit in our result. 
Result so far: 35840.0
Subtract 0 from 689 to get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Step 9:
If we divide 6890 by 784, we get 8 and a remainder of 618.
Use 8 as the next digit of our solution. 
Result so far: 35840.8
The remainder is 618 after subtracting 6272 from 6890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 10:
6180 divided by 784 is 7 with a remainder of 692.
Record the quotient 7 as the next digit in the result. 
Result so far: 35840.87
Deduct 5488 from 6180 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 11:
6920 divided by 784 is 8 with a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 35840.878
The remainder is 648 after subtracting 6272 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 12:
When dividing 6480 by 784, we get 8 with a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 35840.8788
If we subtract 6272 from 6480, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The quotient of the division is 35840.8788, and the remainder is 0.00208.
