We divide 83108087 by 765
The aim is to understand the frequency of 765 in 83108087.

On to step 1:
The number 765 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 765

Let's proceed to step 2:
If we divide 83 by 765, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 765

On to step 3:
765 can be fit into 831 1 times, resulting in a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 765 from 831 to get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 765

Advancing to step 4:
660 divided by 765 is 0 with a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 660, we end up with 660.
Include the next digit (8) from the dividend after 660, then repeat: 6608 / 765

Advancing to step 5:
6608 divided by 765 is 8 with a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Deduct 6120 from 6608 and we're left with 488.
Take the next digit (0) from the dividend and append it to 488, then repeat: 4880 / 765

Advancing to step 6:
If we divide 4880 by 765, we get 6 and a remainder of 290.
Use 6 as the next digit of our solution. 
Result so far: 1086.0
The remainder is 290 after subtracting 4590 from 4880.
Append the next digit (8) from the dividend to 290 and continue with: 2908 / 765

On to step 7:
The number 765 fits into 2908 3 times, leaving a remainder of 613.
The number 3 becomes the next digit in our result. 
Result so far: 10863.0
Subtract 2295 from 2908 to get 613.
Bring next digit (7) of the dividend behind the 613 and repeat the process: 6137 / 765

Going ahead to step 8:
6137 divided by 765 is 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 108638.0
The remainder is 17 after subtracting 6120 from 6137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 765 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 108638.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
If we divide 1700 by 765, we get 2 and a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 108638.02
If we take 1530 away from 1700, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
765 goes into 1700 2 times with a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 108638.022
Subtract 1530 from 1700 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 108638.022 with a remainder of 0.017.
