We look at the division of 363435 by 43 
The aim is to understand the frequency of 43 in 363435.

Going ahead to step 1:
The number 43 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 43

Advancing to step 2:
If we divide 36 by 43, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 43

Moving on to step 3:
When dividing 363 by 43, we get 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 344 from 363, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 43

Going ahead to step 4:
43 goes into 194 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 172 from 194 and we're left with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 43

Going ahead to step 5:
43 goes into 223 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
If we take 215 away from 223, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 43

Let's proceed to step 6:
85 divided by 43 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 8451.0
Subtract 43 from 85 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 8451.9
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
If we divide 330 by 43, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 8451.97
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
290 divided by 43 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 8451.976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 8451.9767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
190 divided by 43 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 8451.97674
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
The number 43 fits into 180 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8451.976744
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 8451.976744 and a remainder of 8e-07.
