Let's divide 21950784 by 856
The aim is to understand the frequency of 856 in 21950784.

Moving on to step 1:
The number 856 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 856

Step 2:
If we divide 21 by 856, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 856

Step 3:
If we divide 219 by 856, we get 0 and a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Include the next digit (5) from the dividend after 219, then repeat: 2195 / 856

On to step 4:
2195 divided by 856 is 2 with a remainder of 483.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1712 from 2195 to get 483.
Take the next digit (0) from the dividend and append it to 483, then repeat: 4830 / 856

On to step 5:
If we divide 4830 by 856, we get 5 and a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 4280 away from 4830, we end up with 550.
Fetch the next digit (7) from the dividend, attach it to 550 and continue: 5507 / 856

On to step 6:
5507 divided by 856 is 6 with a remainder of 371.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
The remainder is 371 after subtracting 5136 from 5507.
Append the next digit (8) from the dividend to 371 and continue with: 3718 / 856

Moving on to step 7:
When dividing 3718 by 856, we get 4 with a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 2564.0
Subtracting 3424 from 3718 leaves us with 294.
Bring next digit (4) of the dividend behind the 294 and repeat the process: 2944 / 856

On to step 8:
If we divide 2944 by 856, we get 3 and a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 25643.0
Subtracting 2568 from 2944 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 9:
3760 divided by 856 is 4 with a remainder of 336.
The next digit of our result is 4. 
Result so far: 25643.4
Deduct 3424 from 3760 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
The number 856 fits into 3360 3 times, leaving a remainder of 792.
Use 3 as the next digit of our solution. 
Result so far: 25643.43
The remainder is 792 after subtracting 2568 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Let's proceed to step 11:
856 goes into 7920 9 times with a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 25643.439
The remainder is 216 after subtracting 7704 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 12:
856 can be fit into 2160 2 times, resulting in a remainder of 448.
The number 2 becomes the next digit in our result. 
Result so far: 25643.4392
Subtract 1712 from 2160 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 13:
856 can be fit into 4480 5 times, resulting in a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 25643.43925
Deduct 4280 from 4480 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
If we divide 2000 by 856, we get 2 and a remainder of 288.
Record the quotient 2 as the next digit in the result. 
Result so far: 25643.439252
If we take 1712 away from 2000, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
If we divide 2880 by 856, we get 3 and a remainder of 312.
Use 3 as the next digit of our solution. 
Result so far: 25643.4392523
If we take 2568 away from 2880, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 16:
If we divide 3120 by 856, we get 3 and a remainder of 552.
Put 3 as the next digit of the answer. 
Result so far: 25643.43925233
If we subtract 2568 from 3120, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 25643.43925233, with a leftover of 5.52e-07.
