768321 divided by 43 
The aim is to understand the frequency of 43 in 768321.

Let's proceed to step 1:
43 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
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 43

Moving on to step 2:
76 divided by 43 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 76, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 43

Let's proceed to step 3:
43 can be fit into 338 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 301 from 338, we get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 43

Advancing to step 4:
When dividing 373 by 43, we get 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Deduct 344 from 373 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 43

On to step 5:
When dividing 292 by 43, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 1786.0
If we take 258 away from 292, we end up with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 43

Let's proceed to step 6:
43 can be fit into 341 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 17867.0
Deduct 301 from 341 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
43 goes into 400 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 17867.9
Subtracting 387 from 400 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
43 goes into 130 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 17867.93
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
43 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 17867.93
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 43, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 17867.9302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
When dividing 140 by 43, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 17867.93023
If we take 129 away from 140, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
When dividing 110 by 43, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 17867.930232
Deduct 86 from 110 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
43 goes into 240 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17867.9302325
Subtracting 215 from 240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
43 goes into 250 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 17867.93023255
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 17867.93023255, with a leftover of 3.5e-08.
