We're dividing 21802884 by 507 
The aim is to understand the frequency of 507 in 21802884.

Going ahead to step 1:
507 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 507

Going ahead to step 2:
507 can be fit into 21 0 times, resulting in 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.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 507

Let's proceed to step 3:
When dividing 218 by 507, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Fetch the next digit (0) from the dividend, attach it to 218 and continue: 2180 / 507

Going ahead to step 4:
507 goes into 2180 4 times with a remainder of 152.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2028 away from 2180, we end up with 152.
Fetch the next digit (2) from the dividend, attach it to 152 and continue: 1522 / 507

Going ahead to step 5:
If we divide 1522 by 507, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 1521 from 1522 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 507

Moving on to step 6:
507 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 430.0
If we take 0 away from 18, we end up with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 507

On to step 7:
The number 507 fits into 188 0 times, leaving a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 4300.0
The remainder is 188 after subtracting 0 from 188.
Append the next digit (4) from the dividend to 188 and continue with: 1884 / 507

Advancing to step 8:
The number 507 fits into 1884 3 times, leaving a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 43003.0
Subtract 1521 from 1884 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 9:
When dividing 3630 by 507, we get 7 with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 43003.7
Subtract 3549 from 3630 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
When dividing 810 by 507, we get 1 with a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 43003.71
Deduct 507 from 810 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 11:
507 goes into 3030 5 times with a remainder of 495.
The next digit of our result is 5. 
Result so far: 43003.715
Deduct 2535 from 3030 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 12:
The number 507 fits into 4950 9 times, leaving a remainder of 387.
The next digit of our result is 9. 
Result so far: 43003.7159
Deduct 4563 from 4950 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 13:
If we divide 3870 by 507, we get 7 and a remainder of 321.
The next digit of our result is 7. 
Result so far: 43003.71597
The remainder is 321 after subtracting 3549 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 14:
If we divide 3210 by 507, we get 6 and a remainder of 168.
The next digit of our result is 6. 
Result so far: 43003.715976
Subtracting 3042 from 3210 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 15:
507 can be fit into 1680 3 times, resulting in a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 43003.7159763
The remainder is 159 after subtracting 1521 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 16:
The number 507 fits into 1590 3 times, leaving a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 43003.71597633
Subtracting 1521 from 1590 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

In conclusion, the division gives 43003.71597633 with a balance of 6.9e-08.
