Let's divide 568550 by 28
The aim is to understand the frequency of 28 in 568550.

Let's proceed to step 1:
When dividing 5 by 28, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 28

Step 2:
28 can be fit into 56 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 56 from 56 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 28

Moving on to step 3:
If we divide 8 by 28, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 28

Advancing to step 4:
When dividing 85 by 28, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 84 away from 85, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 28

Step 5:
The number 28 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 2030.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 28

Moving on to step 6:
28 goes into 150 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20305.0
If we take 140 away from 150, 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:
28 goes into 100 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 20305.3
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 20305.35
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 20305.357
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 20305.3571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 20305.35714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 20305.357142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 20305.3571428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 20305.35714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 20305.35714285 with a remainder of 2e-08.
