76788201 divided by 789 
The aim is to understand the frequency of 789 in 76788201.

Step 1:
789 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 789

Going ahead to step 2:
76 divided by 789 is 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (7) from the dividend to 76 and continue with: 767 / 789

On to step 3:
789 goes into 767 0 times with a remainder of 767.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 767 and we're left with 767.
Fetch the next digit (8) from the dividend, attach it to 767 and continue: 7678 / 789

On to step 4:
789 can be fit into 7678 9 times, resulting in a remainder of 577.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7101 away from 7678, we end up with 577.
Fetch the next digit (8) from the dividend, attach it to 577 and continue: 5778 / 789

Moving on to step 5:
5778 divided by 789 is 7 with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 255 after subtracting 5523 from 5778.
Append the next digit (2) from the dividend to 255 and continue with: 2552 / 789

Going ahead to step 6:
789 can be fit into 2552 3 times, resulting in a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 973.0
Subtract 2367 from 2552 to get 185.
Grab the next digit (0) from the dividend, add it to 185, then carry on: 1850 / 789

Advancing to step 7:
1850 divided by 789 is 2 with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 9732.0
If we subtract 1578 from 1850, we get 272.
Bring next digit (1) of the dividend behind the 272 and repeat the process: 2721 / 789

Let's proceed to step 8:
If we divide 2721 by 789, we get 3 and a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 97323.0
If we take 2367 away from 2721, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
The number 789 fits into 3540 4 times, leaving a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 97323.4
Subtracting 3156 from 3540 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 10:
3840 divided by 789 is 4 with a remainder of 684.
The number 4 becomes the next digit in our result. 
Result so far: 97323.44
Subtract 3156 from 3840 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

The final outcome is 97323.44, with a leftover of 0.684.
