49102912 ÷ 768 
The aim is to understand the frequency of 768 in 49102912.

On to step 1:
When dividing 4 by 768, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 768

On to step 2:
If we divide 49 by 768, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 768

Going ahead to step 3:
768 goes into 491 0 times with a remainder of 491.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 491, we get 491.
Fetch the next digit (0) from the dividend, attach it to 491 and continue: 4910 / 768

Step 4:
768 can be fit into 4910 6 times, resulting in a remainder of 302.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4608 from 4910 and we're left with 302.
Append the next digit (2) from the dividend to 302 and continue with: 3022 / 768

Step 5:
If we divide 3022 by 768, we get 3 and a remainder of 718.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 2304 from 3022 to get 718.
Append the next digit (9) from the dividend to 718 and continue with: 7189 / 768

On to step 6:
768 goes into 7189 9 times with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Deduct 6912 from 7189 and we're left with 277.
Bring next digit (1) of the dividend behind the 277 and repeat the process: 2771 / 768

Let's proceed to step 7:
If we divide 2771 by 768, we get 3 and a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 6393.0
Subtract 2304 from 2771 to get 467.
Take the next digit (2) from the dividend and append it to 467, then repeat: 4672 / 768

Going ahead to step 8:
The number 768 fits into 4672 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 63936.0
If we subtract 4608 from 4672, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
768 goes into 640 0 times with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 63936.0
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
If we divide 6400 by 768, we get 8 and a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 63936.08
If we take 6144 away from 6400, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
If we divide 2560 by 768, we get 3 and a remainder of 256.
Record the quotient 3 as the next digit in the result. 
Result so far: 63936.083
If we subtract 2304 from 2560, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
2560 divided by 768 is 3 with a remainder of 256.
The next digit of our result is 3. 
Result so far: 63936.0833
Subtracting 2304 from 2560 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 63936.0833 with a remainder of 0.00256.
