Let's divide 21868033 by 775
The aim is to understand the frequency of 775 in 21868033.

Going ahead to step 1:
2 divided by 775 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 775

Let's proceed to step 2:
775 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 775

Step 3:
775 goes into 218 0 times with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 775

Going ahead to step 4:
When dividing 2186 by 775, we get 2 with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1550 away from 2186, we end up with 636.
Append the next digit (8) from the dividend to 636 and continue with: 6368 / 775

Going ahead to step 5:
The number 775 fits into 6368 8 times, leaving a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 6200 from 6368 to get 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 775

On to step 6:
775 goes into 1680 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we subtract 1550 from 1680, we get 130.
Include the next digit (3) from the dividend after 130, then repeat: 1303 / 775

On to step 7:
1303 divided by 775 is 1 with a remainder of 528.
Use 1 as the next digit of our solution. 
Result so far: 2821.0
Deduct 775 from 1303 and we're left with 528.
Grab the next digit (3) from the dividend, add it to 528, then carry on: 5283 / 775

Let's proceed to step 8:
The number 775 fits into 5283 6 times, leaving a remainder of 633.
Write down 6 as next digit of the result. 
Result so far: 28216.0
Subtract 4650 from 5283 to get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Moving on to step 9:
775 goes into 6330 8 times with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 28216.8
The remainder is 130 after subtracting 6200 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
1300 divided by 775 is 1 with a remainder of 525.
Use 1 as the next digit of our solution. 
Result so far: 28216.81
If we subtract 775 from 1300, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 11:
775 goes into 5250 6 times with a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 28216.816
Subtract 4650 from 5250 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
The number 775 fits into 6000 7 times, leaving a remainder of 575.
Use 7 as the next digit of our solution. 
Result so far: 28216.8167
The remainder is 575 after subtracting 5425 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 13:
When dividing 5750 by 775, we get 7 with a remainder of 325.
The number 7 becomes the next digit in our result. 
Result so far: 28216.81677
Subtracting 5425 from 5750 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final result is 28216.81677 with a remainder of 0.000325.
