21480754 ÷ 568 
The aim is to understand the frequency of 568 in 21480754.

Moving on to step 1:
2 divided by 568 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 568

On to step 2:
The number 568 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 568

Step 3:
568 goes into 214 0 times with a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 214 after subtracting 0 from 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 568

On to step 4:
If we divide 2148 by 568, we get 3 and a remainder of 444.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1704 away from 2148, we end up with 444.
Append the next digit (0) from the dividend to 444 and continue with: 4440 / 568

Advancing to step 5:
568 goes into 4440 7 times with a remainder of 464.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 3976 from 4440, we get 464.
Grab the next digit (7) from the dividend, add it to 464, then carry on: 4647 / 568

Moving on to step 6:
4647 divided by 568 is 8 with a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 378.0
If we take 4544 away from 4647, we end up with 103.
Bring next digit (5) of the dividend behind the 103 and repeat the process: 1035 / 568

Going ahead to step 7:
1035 divided by 568 is 1 with a remainder of 467.
Use 1 as the next digit of our solution. 
Result so far: 3781.0
The remainder is 467 after subtracting 568 from 1035.
Bring next digit (4) of the dividend behind the 467 and repeat the process: 4674 / 568

Advancing to step 8:
4674 divided by 568 is 8 with a remainder of 130.
Record the quotient 8 as the next digit in the result. 
Result so far: 37818.0
Subtract 4544 from 4674 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
568 can be fit into 1300 2 times, resulting in a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 37818.2
Subtract 1136 from 1300 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
When dividing 1640 by 568, we get 2 with a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 37818.22
Deduct 1136 from 1640 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Our division results in 37818.22 with a remaining 0.504.
