We look at the division of 768745 by 43 
The aim is to understand the frequency of 43 in 768745.

Moving on to step 1:
When dividing 7 by 43, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 43

On to step 2:
If we divide 76 by 43, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 43 from 76, we get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 43

Moving on to step 3:
43 goes into 338 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 301 from 338, we get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 43

On to step 4:
43 can be fit into 377 8 times, resulting in a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we take 344 away from 377, we end up with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 43

Going ahead to step 5:
When dividing 334 by 43, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 1787.0
Deduct 301 from 334 and we're left with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 43

Going ahead to step 6:
335 divided by 43 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 17877.0
Deduct 301 from 335 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 43, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 17877.7
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 43, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 17877.79
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
43 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 17877.79
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 17877.7906
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
43 goes into 420 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 17877.79069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
When dividing 330 by 43, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 17877.790697
Deduct 301 from 330 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 17877.7906976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 17877.79069767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 17877.79069767 with a remainder of 1.9e-08.
