We look at the division of 387788 by 43 
The aim is to understand the frequency of 43 in 387788.

Going ahead to step 1:
3 divided by 43 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 43

Step 2:
When dividing 38 by 43, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 43

Advancing to step 3:
387 divided by 43 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 387 away from 387, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 43

On to step 4:
43 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 43

Advancing to step 5:
43 goes into 78 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
Deduct 43 from 78 and we're left with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 43

Moving on to step 6:
358 divided by 43 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 9018.0
The remainder is 14 after subtracting 344 from 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
140 divided by 43 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 9018.3
Subtract 129 from 140 to get 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 8:
43 can be fit into 110 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9018.32
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.

Going ahead to step 9:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9018.325
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9018.3255
Deduct 215 from 250 and we're left 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 final outcome is 9018.3255, with a leftover of 0.00035.
