We're dividing 907182 by 43 
The aim is to understand the frequency of 43 in 907182.

On to step 1:
43 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 43

Advancing to step 2:
90 divided by 43 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 86 away from 90, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 43

Let's proceed to step 3:
43 can be fit into 47 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 4 after subtracting 43 from 47.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 43

Step 4:
41 divided by 43 is 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtracting 0 from 41 leaves us with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 43

Moving on to step 5:
The number 43 fits into 418 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 2109.0
Subtract 387 from 418 to get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 43

On to step 6:
The number 43 fits into 312 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 21097.0
Subtracting 301 from 312 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.

On to step 7:
110 divided by 43 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 21097.2
Subtracting 86 from 110 leaves us 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.

On to step 8:
The number 43 fits into 240 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 21097.25
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 9:
If we divide 250 by 43, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 21097.255
Subtract 215 from 250 to get 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 final result is 21097.255 with a remainder of 0.0035.
