We're dividing 753681 by 43 
The aim is to understand the frequency of 43 in 753681.

Going ahead to step 1:
7 divided by 43 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 43

Let's proceed to step 2:
The number 43 fits into 75 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 75, we end up with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 43

Step 3:
43 can be fit into 323 7 times, resulting in a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 301 from 323, we get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 43

On to step 4:
43 can be fit into 226 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we subtract 215 from 226, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 43

Step 5:
43 can be fit into 118 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1752.0
Subtract 86 from 118 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 43

Step 6:
43 goes into 321 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17527.0
The remainder is 20 after subtracting 301 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 17527.4
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 43 fits into 280 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 17527.46
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
43 goes into 220 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 17527.465
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 17527.4651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
43 goes into 70 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 17527.46511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 17527.46511 and a remainder of 2.7e-05.
