2176761 divided by 778 
The aim is to understand the frequency of 778 in 2176761.

Step 1:
When dividing 2 by 778, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 778

Step 2:
When dividing 21 by 778, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 778

On to step 3:
When dividing 217 by 778, we get 0 with a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Take the next digit (6) from the dividend and append it to 217, then repeat: 2176 / 778

Step 4:
When dividing 2176 by 778, we get 2 with a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1556 from 2176 and we're left with 620.
Append the next digit (7) from the dividend to 620 and continue with: 6207 / 778

Advancing to step 5:
If we divide 6207 by 778, we get 7 and a remainder of 761.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 5446 from 6207 to get 761.
Take the next digit (6) from the dividend and append it to 761, then repeat: 7616 / 778

Let's proceed to step 6:
778 can be fit into 7616 9 times, resulting in a remainder of 614.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Subtracting 7002 from 7616 leaves us with 614.
Append the next digit (1) from the dividend to 614 and continue with: 6141 / 778

Advancing to step 7:
6141 divided by 778 is 7 with a remainder of 695.
The number 7 becomes the next digit in our result. 
Result so far: 2797.0
Subtract 5446 from 6141 to get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Moving on to step 8:
The number 778 fits into 6950 8 times, leaving a remainder of 726.
The number 8 becomes the next digit in our result. 
Result so far: 2797.8
Subtract 6224 from 6950 to get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 9:
7260 divided by 778 is 9 with a remainder of 258.
The number 9 becomes the next digit in our result. 
Result so far: 2797.89
Subtracting 7002 from 7260 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 10:
778 can be fit into 2580 3 times, resulting in a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 2797.893
If we subtract 2334 from 2580, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 11:
If we divide 2460 by 778, we get 3 and a remainder of 126.
The next digit of our result is 3. 
Result so far: 2797.8933
The remainder is 126 after subtracting 2334 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 2797.8933 with a remainder of 0.00126.
