We're dividing 76805864 by 788 
The aim is to understand the frequency of 788 in 76805864.

Advancing to step 1:
If we divide 7 by 788, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 788

Let's proceed to step 2:
76 divided by 788 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 788

Going ahead to step 3:
788 can be fit into 768 0 times, resulting in a remainder of 768.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 768 after subtracting 0 from 768.
Bring next digit (0) of the dividend behind the 768 and repeat the process: 7680 / 788

Step 4:
7680 divided by 788 is 9 with a remainder of 588.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 7092 from 7680, we get 588.
Fetch the next digit (5) from the dividend, attach it to 588 and continue: 5885 / 788

On to step 5:
788 can be fit into 5885 7 times, resulting in a remainder of 369.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 5516 from 5885 and we're left with 369.
Grab the next digit (8) from the dividend, add it to 369, then carry on: 3698 / 788

Step 6:
788 goes into 3698 4 times with a remainder of 546.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
Deduct 3152 from 3698 and we're left with 546.
Append the next digit (6) from the dividend to 546 and continue with: 5466 / 788

Moving on to step 7:
When dividing 5466 by 788, we get 6 with a remainder of 738.
Put 6 as the next digit of the answer. 
Result so far: 9746.0
Deduct 4728 from 5466 and we're left with 738.
Grab the next digit (4) from the dividend, add it to 738, then carry on: 7384 / 788

On to step 8:
788 goes into 7384 9 times with a remainder of 292.
Write down 9 as next digit of the result. 
Result so far: 97469.0
Deduct 7092 from 7384 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 9:
788 goes into 2920 3 times with a remainder of 556.
The next digit of our result is 3. 
Result so far: 97469.3
Subtract 2364 from 2920 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 10:
The number 788 fits into 5560 7 times, leaving a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 97469.37
Deduct 5516 from 5560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
788 goes into 440 0 times with a remainder of 440.
The next digit of our result is 0. 
Result so far: 97469.37
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
4400 divided by 788 is 5 with a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 97469.3705
Subtract 3940 from 4400 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
If we divide 4600 by 788, we get 5 and a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 97469.37055
Subtract 3940 from 4600 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The final result is 97469.37055 with a remainder of 0.00066.
