363926 ÷ 43 
The aim is to understand the frequency of 43 in 363926.

On to step 1:
43 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 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.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 43

Advancing to step 3:
43 goes into 363 8 times with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 344 from 363 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 43

On to step 4:
43 can be fit into 199 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 172 from 199 and we're left with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 43

Going ahead to step 5:
When dividing 272 by 43, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 846.0
Deduct 258 from 272 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 43

On to step 6:
When dividing 146 by 43, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 8463.0
Deduct 129 from 146 and we're left 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.

Let's proceed to step 7:
The number 43 fits into 170 3 times, leaving a remainder of 41.
The next digit of our result is 3. 
Result so far: 8463.3
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 8:
43 goes into 410 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 8463.39
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.

Moving on to step 9:
The number 43 fits into 230 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 8463.395
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.

Moving on to step 10:
150 divided by 43 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 8463.3953
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 11:
When dividing 210 by 43, we get 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 8463.39534
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.

Step 12:
If we divide 380 by 43, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8463.395348
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.

Moving on to step 13:
The number 43 fits into 360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 8463.3953488
The remainder is 16 after subtracting 344 from 360.
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 outcome is 8463.3953488, with a leftover of 1.6e-07.
