We're dividing 159785 by 43 
The aim is to understand the frequency of 43 in 159785.

Advancing to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 43

Advancing to step 2:
When dividing 15 by 43, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 43

Advancing to step 3:
When dividing 159 by 43, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 30 after subtracting 129 from 159.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 43

On to step 4:
43 goes into 307 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 301 from 307 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 43

On to step 5:
68 divided by 43 is 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 371.0
Subtracting 43 from 68 leaves us with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 43

Moving on to step 6:
43 goes into 255 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 3715.0
Subtract 215 from 255 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
The number 43 fits into 400 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 3715.9
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.

Step 8:
If we divide 130 by 43, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3715.93
Subtracting 129 from 130 leaves us with 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:
If we divide 10 by 43, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 3715.93
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
43 goes into 100 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 3715.9302
Subtracting 86 from 100 leaves us 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.

Let's proceed to step 11:
The number 43 fits into 140 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 3715.93023
Subtracting 129 from 140 leaves us 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:
43 goes into 110 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3715.930232
If we subtract 86 from 110, we get 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:
The number 43 fits into 240 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 3715.9302325
Subtract 215 from 240 to 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.

Let's proceed to step 14:
250 divided by 43 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3715.93023255
Subtracting 215 from 250 leaves us 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.

After the division, we end up with 3715.93023255 and a remainder of 3.5e-08.
