Let's divide 20840780 by 572
The aim is to understand the frequency of 572 in 20840780.

Advancing to step 1:
If we divide 2 by 572, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 572

Let's proceed to step 2:
572 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 572

Advancing to step 3:
If we divide 208 by 572, we get 0 and a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Fetch the next digit (4) from the dividend, attach it to 208 and continue: 2084 / 572

On to step 4:
If we divide 2084 by 572, we get 3 and a remainder of 368.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1716 from 2084, we get 368.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 572

Going ahead to step 5:
When dividing 3680 by 572, we get 6 with a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 3432 from 3680, we get 248.
Grab the next digit (7) from the dividend, add it to 248, then carry on: 2487 / 572

Going ahead to step 6:
572 goes into 2487 4 times with a remainder of 199.
Put 4 as the next digit of the answer. 
Result so far: 364.0
If we take 2288 away from 2487, we end up with 199.
Append the next digit (8) from the dividend to 199 and continue with: 1998 / 572

Going ahead to step 7:
If we divide 1998 by 572, we get 3 and a remainder of 282.
Use 3 as the next digit of our solution. 
Result so far: 3643.0
Subtracting 1716 from 1998 leaves us with 282.
Bring next digit (0) of the dividend behind the 282 and repeat the process: 2820 / 572

On to step 8:
572 goes into 2820 4 times with a remainder of 532.
The number 4 becomes the next digit in our result. 
Result so far: 36434.0
If we subtract 2288 from 2820, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 9:
572 goes into 5320 9 times with a remainder of 172.
The next digit of our result is 9. 
Result so far: 36434.9
The remainder is 172 after subtracting 5148 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
572 can be fit into 1720 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 36434.93
If we subtract 1716 from 1720, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 572, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 36434.93
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
400 divided by 572 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 36434.93
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 36434.93 with a remaining 0.004.
