43568832 divided by 40 
The aim is to understand the frequency of 40 in 43568832.

Going ahead to step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 40

Moving on to step 2:
40 goes into 43 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 40 from 43.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 40

Moving on to step 3:
The number 40 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 40

Let's proceed to step 4:
40 can be fit into 356 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 320 away from 356, we end up with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 40

Moving on to step 5:
If we divide 368 by 40, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
The remainder is 8 after subtracting 360 from 368.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 40

Let's proceed to step 6:
If we divide 88 by 40, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 10892.0
Subtracting 80 from 88 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 40

Moving on to step 7:
83 divided by 40 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 108922.0
The remainder is 3 after subtracting 80 from 83.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 40

Going ahead to step 8:
If we divide 32 by 40, we get 0 and a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 1089220.0
Subtracting 0 from 32 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 40, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1089220.8
If we subtract 320 from 320, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1089220.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1089220.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1089220.8 with a remaining 0.0.
