We're dividing 748155 by 43 
The aim is to understand the frequency of 43 in 748155.

Going ahead to step 1:
7 divided by 43 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 43

Step 2:
The number 43 fits into 74 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 31 after subtracting 43 from 74.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 43

Advancing to step 3:
When dividing 318 by 43, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 17.0
If we take 301 away from 318, we end up with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 43

Step 4:
If we divide 171 by 43, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 173.0
If we take 129 away from 171, we end up with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 43

Advancing to step 5:
43 goes into 425 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1739.0
Subtract 387 from 425 to get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 43

Going ahead to step 6:
43 goes into 385 8 times with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 17398.0
Subtracting 344 from 385 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
410 divided by 43 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 17398.9
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
43 can be fit into 230 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 17398.95
If we subtract 215 from 230, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 43 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 17398.953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
43 can be fit into 210 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 17398.9534
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
380 divided by 43 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 17398.95348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 43 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17398.953488
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 17398.953488 with a remainder of 1.6e-06.
