We're dividing 71807039 by 765 
The aim is to understand the frequency of 765 in 71807039.

Let's proceed to step 1:
765 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 765

Going ahead to step 2:
If we divide 71 by 765, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 765

Let's proceed to step 3:
765 can be fit into 718 0 times, resulting in a remainder of 718.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 718 after subtracting 0 from 718.
Include the next digit (0) from the dividend after 718, then repeat: 7180 / 765

Step 4:
7180 divided by 765 is 9 with a remainder of 295.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6885 away from 7180, we end up with 295.
Take the next digit (7) from the dividend and append it to 295, then repeat: 2957 / 765

On to step 5:
The number 765 fits into 2957 3 times, leaving a remainder of 662.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 2295 from 2957 leaves us with 662.
Take the next digit (0) from the dividend and append it to 662, then repeat: 6620 / 765

Going ahead to step 6:
The number 765 fits into 6620 8 times, leaving a remainder of 500.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
If we subtract 6120 from 6620, we get 500.
Grab the next digit (3) from the dividend, add it to 500, then carry on: 5003 / 765

Advancing to step 7:
When dividing 5003 by 765, we get 6 with a remainder of 413.
Use 6 as the next digit of our solution. 
Result so far: 9386.0
If we take 4590 away from 5003, we end up with 413.
Bring next digit (9) of the dividend behind the 413 and repeat the process: 4139 / 765

Let's proceed to step 8:
765 can be fit into 4139 5 times, resulting in a remainder of 314.
Write down 5 as next digit of the result. 
Result so far: 93865.0
The remainder is 314 after subtracting 3825 from 4139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
3140 divided by 765 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 93865.4
The remainder is 80 after subtracting 3060 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 765 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 93865.41
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 765, we get 0 with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 93865.41
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 12:
765 goes into 3500 4 times with a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 93865.4104
Deduct 3060 from 3500 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.

Moving on to step 13:
765 goes into 4400 5 times with a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 93865.41045
Subtracting 3825 from 4400 leaves us with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 14:
When dividing 5750 by 765, we get 7 with a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 93865.410457
Deduct 5355 from 5750 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 15:
765 can be fit into 3950 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 93865.4104575
Deduct 3825 from 3950 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 16:
765 goes into 1250 1 times with a remainder of 485.
The number 1 becomes the next digit in our result. 
Result so far: 93865.41045751
Deduct 765 from 1250 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final outcome is 93865.41045751, with a leftover of 4.85e-07.
