We're dividing 516723 by 43 
The aim is to understand the frequency of 43 in 516723.

Let's proceed to step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 43

Going ahead to step 2:
51 divided by 43 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 51, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 43

Advancing to step 3:
If we divide 86 by 43, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 86 from 86 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 43

Advancing to step 4:
When dividing 7 by 43, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 43

Moving on to step 5:
43 can be fit into 72 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1201.0
Subtract 43 from 72 to get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 43

Step 6:
When dividing 293 by 43, we get 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 12016.0
If we subtract 258 from 293, we 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.

Going ahead to step 7:
43 can be fit into 350 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 12016.8
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 43 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 12016.81
If we take 43 away from 60, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
If we divide 170 by 43, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 12016.813
If we subtract 129 from 170, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
43 goes into 410 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 12016.8139
If we take 387 away from 410, we end up 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.

Step 11:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12016.81395
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 12016.813953
Deduct 129 from 150 and we're left with 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 13:
43 goes into 210 4 times with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 12016.8139534
Subtracting 172 from 210 leaves us 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.

Step 14:
43 goes into 380 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 12016.81395348
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 12016.81395348 and a remainder of 3.6e-08.
