We're dividing 774096 by 51 
The aim is to understand the frequency of 51 in 774096.

Advancing to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 51

Step 2:
When dividing 77 by 51, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 77 leaves us with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 51

On to step 3:
When dividing 264 by 51, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 9 after subtracting 255 from 264.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 51

Going ahead to step 4:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we subtract 51 from 90, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 51

Moving on to step 5:
When dividing 399 by 51, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 1517.0
Subtract 357 from 399 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 51

Step 6:
426 divided by 51 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 15178.0
If we take 408 away from 426, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
51 goes into 180 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 15178.3
If we take 153 away from 180, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
270 divided by 51 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15178.35
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 51 fits into 150 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 15178.352
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 51, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 15178.3529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
If we divide 210 by 51, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 15178.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
When dividing 60 by 51, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 15178.352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
90 divided by 51 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 15178.3529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 15178.3529411 with a remainder of 3.9e-07.
