We look at the division of 760049 by 43 
The aim is to understand the frequency of 43 in 760049.

Advancing to step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 43

Step 2:
43 goes into 76 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 43 from 76 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 43

Step 3:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 301 from 330, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 43

Step 4:
290 divided by 43 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Subtract 258 from 290 to get 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 43

Moving on to step 5:
43 can be fit into 324 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1767.0
If we take 301 away from 324, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 43

Going ahead to step 6:
When dividing 239 by 43, we get 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 17675.0
Deduct 215 from 239 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.

Step 7:
43 goes into 240 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 17675.5
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
The number 43 fits into 250 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 17675.55
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 17675.55, and the remainder is 0.035.
