68117789 ÷ 789 
The aim is to understand the frequency of 789 in 68117789.

Going ahead to step 1:
If we divide 6 by 789, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 789

Moving on to step 2:
When dividing 68 by 789, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 789

Step 3:
The number 789 fits into 681 0 times, leaving a remainder of 681.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 681 and we're left with 681.
Fetch the next digit (1) from the dividend, attach it to 681 and continue: 6811 / 789

Step 4:
789 goes into 6811 8 times with a remainder of 499.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6312 from 6811 leaves us with 499.
Fetch the next digit (7) from the dividend, attach it to 499 and continue: 4997 / 789

Step 5:
789 goes into 4997 6 times with a remainder of 263.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 263 after subtracting 4734 from 4997.
Bring next digit (7) of the dividend behind the 263 and repeat the process: 2637 / 789

Step 6:
2637 divided by 789 is 3 with a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
If we take 2367 away from 2637, we end up with 270.
Grab the next digit (8) from the dividend, add it to 270, then carry on: 2708 / 789

Let's proceed to step 7:
789 goes into 2708 3 times with a remainder of 341.
The number 3 becomes the next digit in our result. 
Result so far: 8633.0
Subtracting 2367 from 2708 leaves us with 341.
Include the next digit (9) from the dividend after 341, then repeat: 3419 / 789

Moving on to step 8:
If we divide 3419 by 789, we get 4 and a remainder of 263.
Put 4 as the next digit of the answer. 
Result so far: 86334.0
Deduct 3156 from 3419 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
The number 789 fits into 2630 3 times, leaving a remainder of 263.
The next digit of our result is 3. 
Result so far: 86334.3
If we take 2367 away from 2630, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 10:
789 can be fit into 2630 3 times, resulting in a remainder of 263.
The next digit of our result is 3. 
Result so far: 86334.33
If we take 2367 away from 2630, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 86334.33, with a leftover of 0.263.
