Let's divide 99623 by 43
The aim is to understand the frequency of 43 in 99623.

Going ahead to step 1:
43 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 43

Let's proceed to step 2:
The number 43 fits into 99 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 86 from 99, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 43

Advancing to step 3:
43 can be fit into 136 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 7 after subtracting 129 from 136.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 43

On to step 4:
If we divide 72 by 43, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 231.0
If we subtract 43 from 72, we get 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 43

Moving on to step 5:
43 can be fit into 293 6 times, resulting in a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 2316.0
If we take 258 away from 293, we end up 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.

Let's proceed to step 6:
43 goes into 350 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2316.8
Deduct 344 from 350 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 43, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 2316.81
The remainder is 17 after subtracting 43 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
43 can be fit into 170 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 2316.813
Subtract 129 from 170 to 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.

Let's proceed to step 9:
410 divided by 43 is 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 2316.8139
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.

On to step 10:
230 divided by 43 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2316.81395
If we take 215 away from 230, we end up with 15.
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 11:
The number 43 fits into 150 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 2316.813953
Subtract 129 from 150 to 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 12:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 2316.8139534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 2316.81395348
Deduct 344 from 380 and we're left 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.

Our division results in 2316.81395348 with a remaining 3.6e-08.
