We're dividing 13350 by 43 
The aim is to understand the frequency of 43 in 13350.

Let's proceed to step 1:
43 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 43

Moving on to step 2:
43 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 43

Advancing to step 3:
43 goes into 133 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 129 from 133 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 43

Let's proceed to step 4:
If we divide 45 by 43, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 43 from 45, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 43

Step 5:
20 divided by 43 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 310.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 6:
200 divided by 43 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 310.4
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
43 can be fit into 280 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 310.46
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
220 divided by 43 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 310.465
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 310.4651
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 43 fits into 70 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 310.46511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 310.46511, and the remainder is 2.7e-05.
