We divide 20721687 by 785
The aim is to understand the frequency of 785 in 20721687.

Going ahead to step 1:
The number 785 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 785

On to step 2:
785 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 785

On to step 3:
785 goes into 207 0 times with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 207 to get 207.
Bring next digit (2) of the dividend behind the 207 and repeat the process: 2072 / 785

Advancing to step 4:
785 can be fit into 2072 2 times, resulting in a remainder of 502.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1570 from 2072 to get 502.
Take the next digit (1) from the dividend and append it to 502, then repeat: 5021 / 785

Moving on to step 5:
When dividing 5021 by 785, we get 6 with a remainder of 311.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 311 after subtracting 4710 from 5021.
Bring next digit (6) of the dividend behind the 311 and repeat the process: 3116 / 785

Moving on to step 6:
785 can be fit into 3116 3 times, resulting in a remainder of 761.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Deduct 2355 from 3116 and we're left with 761.
Include the next digit (8) from the dividend after 761, then repeat: 7618 / 785

Let's proceed to step 7:
7618 divided by 785 is 9 with a remainder of 553.
Write down 9 as next digit of the result. 
Result so far: 2639.0
If we take 7065 away from 7618, we end up with 553.
Include the next digit (7) from the dividend after 553, then repeat: 5537 / 785

Advancing to step 8:
If we divide 5537 by 785, we get 7 and a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 26397.0
Subtract 5495 from 5537 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
785 goes into 420 0 times with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 26397.0
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
785 goes into 4200 5 times with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 26397.05
Subtracting 3925 from 4200 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
785 can be fit into 2750 3 times, resulting in a remainder of 395.
Write down 3 as next digit of the result. 
Result so far: 26397.053
If we take 2355 away from 2750, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 12:
When dividing 3950 by 785, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 26397.0535
The remainder is 25 after subtracting 3925 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
The number 785 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 26397.0535
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
785 can be fit into 2500 3 times, resulting in a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 26397.053503
Subtracting 2355 from 2500 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 15:
When dividing 1450 by 785, we get 1 with a remainder of 665.
Write down 1 as next digit of the result. 
Result so far: 26397.0535031
If we subtract 785 from 1450, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

On to step 16:
If we divide 6650 by 785, we get 8 and a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 26397.05350318
If we take 6280 away from 6650, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 26397.05350318 with a remainder of 3.7e-07.
