21025363 ÷ 529 
The aim is to understand the frequency of 529 in 21025363.

Moving on to step 1:
529 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 529

On to step 2:
21 divided by 529 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 529

On to step 3:
When dividing 210 by 529, we get 0 with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Append the next digit (2) from the dividend to 210 and continue with: 2102 / 529

Advancing to step 4:
When dividing 2102 by 529, we get 3 with a remainder of 515.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1587 from 2102 leaves us with 515.
Grab the next digit (5) from the dividend, add it to 515, then carry on: 5155 / 529

Advancing to step 5:
529 goes into 5155 9 times with a remainder of 394.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 394 after subtracting 4761 from 5155.
Grab the next digit (3) from the dividend, add it to 394, then carry on: 3943 / 529

Let's proceed to step 6:
The number 529 fits into 3943 7 times, leaving a remainder of 240.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
The remainder is 240 after subtracting 3703 from 3943.
Append the next digit (6) from the dividend to 240 and continue with: 2406 / 529

Moving on to step 7:
The number 529 fits into 2406 4 times, leaving a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 3974.0
Subtracting 2116 from 2406 leaves us with 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 529

Advancing to step 8:
When dividing 2903 by 529, we get 5 with a remainder of 258.
Put 5 as the next digit of the answer. 
Result so far: 39745.0
The remainder is 258 after subtracting 2645 from 2903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 9:
The number 529 fits into 2580 4 times, leaving a remainder of 464.
Write down 4 as next digit of the result. 
Result so far: 39745.4
The remainder is 464 after subtracting 2116 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 10:
529 can be fit into 4640 8 times, resulting in a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 39745.48
Subtract 4232 from 4640 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 11:
529 goes into 4080 7 times with a remainder of 377.
The next digit of our result is 7. 
Result so far: 39745.487
Deduct 3703 from 4080 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 12:
When dividing 3770 by 529, we get 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 39745.4877
Subtracting 3703 from 3770 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 39745.4877 with a remaining 0.00067.
