We're dividing 905792 by 43 
The aim is to understand the frequency of 43 in 905792.

Advancing to step 1:
9 divided by 43 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 43

Step 2:
43 goes into 90 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 86 from 90 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 43

Moving on to step 3:
43 can be fit into 45 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 43 from 45, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 43

Let's proceed to step 4:
When dividing 27 by 43, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 43

Step 5:
279 divided by 43 is 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 2106.0
Subtract 258 from 279 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 43

Moving on to step 6:
43 goes into 212 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 21064.0
Deduct 172 from 212 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
The number 43 fits into 400 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 21064.9
Deduct 387 from 400 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
If we divide 130 by 43, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 21064.93
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 43, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 21064.93
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 43, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 21064.9302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 43, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 21064.93023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
110 divided by 43 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 21064.930232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
If we divide 240 by 43, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 21064.9302325
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
The number 43 fits into 250 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 21064.93023255
Subtracting 215 from 250 leaves us 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.

The final outcome is 21064.93023255, with a leftover of 3.5e-08.
