74987709 ÷ 765 
The aim is to understand the frequency of 765 in 74987709.

Advancing to step 1:
7 divided by 765 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 765

Step 2:
When dividing 74 by 765, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 765

Let's proceed to step 3:
765 can be fit into 749 0 times, resulting in a remainder of 749.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 749, we get 749.
Include the next digit (8) from the dividend after 749, then repeat: 7498 / 765

Step 4:
If we divide 7498 by 765, we get 9 and a remainder of 613.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 6885 from 7498 leaves us with 613.
Bring next digit (7) of the dividend behind the 613 and repeat the process: 6137 / 765

Step 5:
765 goes into 6137 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 6120 from 6137 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 765

Advancing to step 6:
If we divide 177 by 765, we get 0 and a remainder of 177.
The next digit of our result is 0. 
Result so far: 980.0
If we take 0 away from 177, we end up with 177.
Append the next digit (0) from the dividend to 177 and continue with: 1770 / 765

On to step 7:
When dividing 1770 by 765, we get 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 9802.0
Subtract 1530 from 1770 to get 240.
Grab the next digit (9) from the dividend, add it to 240, then carry on: 2409 / 765

Let's proceed to step 8:
2409 divided by 765 is 3 with a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 98023.0
If we take 2295 away from 2409, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
If we divide 1140 by 765, we get 1 and a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 98023.1
Subtract 765 from 1140 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 10:
If we divide 3750 by 765, we get 4 and a remainder of 690.
Use 4 as the next digit of our solution. 
Result so far: 98023.14
If we take 3060 away from 3750, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 11:
6900 divided by 765 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 98023.149
Subtract 6885 from 6900 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 765, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 98023.149
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
The number 765 fits into 1500 1 times, leaving a remainder of 735.
The next digit of our result is 1. 
Result so far: 98023.14901
Subtracting 765 from 1500 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

On to step 14:
When dividing 7350 by 765, we get 9 with a remainder of 465.
The next digit of our result is 9. 
Result so far: 98023.149019
The remainder is 465 after subtracting 6885 from 7350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 15:
The number 765 fits into 4650 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 98023.1490196
If we subtract 4590 from 4650, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
765 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 98023.1490196
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 98023.1490196 with a remaining 6e-07.
