Let's divide 43915443 by 765
The aim is to understand the frequency of 765 in 43915443.

Advancing to step 1:
4 divided by 765 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 765

On to step 2:
765 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 765

Step 3:
439 divided by 765 is 0 with a remainder of 439.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 439 to get 439.
Bring next digit (1) of the dividend behind the 439 and repeat the process: 4391 / 765

Let's proceed to step 4:
The number 765 fits into 4391 5 times, leaving a remainder of 566.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 3825 from 4391, we get 566.
Grab the next digit (5) from the dividend, add it to 566, then carry on: 5665 / 765

On to step 5:
765 goes into 5665 7 times with a remainder of 310.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 5355 from 5665 leaves us with 310.
Fetch the next digit (4) from the dividend, attach it to 310 and continue: 3104 / 765

Moving on to step 6:
If we divide 3104 by 765, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
The remainder is 44 after subtracting 3060 from 3104.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 765

Going ahead to step 7:
444 divided by 765 is 0 with a remainder of 444.
Write down 0 as next digit of the result. 
Result so far: 5740.0
If we take 0 away from 444, we end up with 444.
Grab the next digit (3) from the dividend, add it to 444, then carry on: 4443 / 765

Moving on to step 8:
The number 765 fits into 4443 5 times, leaving a remainder of 618.
Put 5 as the next digit of the answer. 
Result so far: 57405.0
Subtracting 3825 from 4443 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 9:
765 can be fit into 6180 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 57405.8
If we subtract 6120 from 6180, 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.

Advancing to step 10:
765 goes into 600 0 times with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 57405.8
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
765 goes into 6000 7 times with a remainder of 645.
Write down 7 as next digit of the result. 
Result so far: 57405.807
If we subtract 5355 from 6000, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 12:
When dividing 6450 by 765, we get 8 with a remainder of 330.
Record the quotient 8 as the next digit in the result. 
Result so far: 57405.8078
If we subtract 6120 from 6450, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
The number 765 fits into 3300 4 times, leaving a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 57405.80784
If we take 3060 away from 3300, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
If we divide 2400 by 765, we get 3 and a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 57405.807843
Subtracting 2295 from 2400 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 15:
If we divide 1050 by 765, we get 1 and a remainder of 285.
The next digit of our result is 1. 
Result so far: 57405.8078431
Subtract 765 from 1050 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 16:
When dividing 2850 by 765, we get 3 with a remainder of 555.
The next digit of our result is 3. 
Result so far: 57405.80784313
If we take 2295 away from 2850, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final outcome is 57405.80784313, with a leftover of 5.55e-07.
