We look at the division of 26880398 by 779 
The aim is to understand the frequency of 779 in 26880398.

Going ahead to step 1:
779 can be fit into 2 0 times, resulting in 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.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 779

Advancing to step 2:
The number 779 fits into 26 0 times, leaving a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 779

On to step 3:
268 divided by 779 is 0 with a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 268 after subtracting 0 from 268.
Bring next digit (8) of the dividend behind the 268 and repeat the process: 2688 / 779

On to step 4:
779 goes into 2688 3 times with a remainder of 351.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2337 from 2688, we get 351.
Take the next digit (0) from the dividend and append it to 351, then repeat: 3510 / 779

On to step 5:
779 goes into 3510 4 times with a remainder of 394.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 3116 from 3510, we get 394.
Bring next digit (3) of the dividend behind the 394 and repeat the process: 3943 / 779

Advancing to step 6:
779 goes into 3943 5 times with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Subtracting 3895 from 3943 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 779

Advancing to step 7:
779 can be fit into 489 0 times, resulting in a remainder of 489.
Write down 0 as next digit of the result. 
Result so far: 3450.0
Subtracting 0 from 489 leaves us with 489.
Fetch the next digit (8) from the dividend, attach it to 489 and continue: 4898 / 779

Going ahead to step 8:
779 goes into 4898 6 times with a remainder of 224.
The next digit of our result is 6. 
Result so far: 34506.0
Deduct 4674 from 4898 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
If we divide 2240 by 779, we get 2 and a remainder of 682.
Put 2 as the next digit of the answer. 
Result so far: 34506.2
If we subtract 1558 from 2240, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 10:
When dividing 6820 by 779, we get 8 with a remainder of 588.
Write down 8 as next digit of the result. 
Result so far: 34506.28
The remainder is 588 after subtracting 6232 from 6820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 11:
779 goes into 5880 7 times with a remainder of 427.
The next digit of our result is 7. 
Result so far: 34506.287
Subtracting 5453 from 5880 leaves us with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 12:
4270 divided by 779 is 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 34506.2875
Subtract 3895 from 4270 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 13:
When dividing 3750 by 779, we get 4 with a remainder of 634.
The number 4 becomes the next digit in our result. 
Result so far: 34506.28754
Subtract 3116 from 3750 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 14:
If we divide 6340 by 779, we get 8 and a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 34506.287548
The remainder is 108 after subtracting 6232 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
779 can be fit into 1080 1 times, resulting in a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 34506.2875481
The remainder is 301 after subtracting 779 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 16:
779 can be fit into 3010 3 times, resulting in a remainder of 673.
Use 3 as the next digit of our solution. 
Result so far: 34506.28754813
Subtracting 2337 from 3010 leaves us with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

The final result is 34506.28754813 with a remainder of 6.73e-07.
