243629 ÷ 40 
The aim is to understand the frequency of 40 in 243629.

Moving on to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 40

Advancing to step 2:
40 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 40

Let's proceed to step 3:
40 goes into 243 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 240 from 243, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 40

Moving on to step 4:
36 divided by 40 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 40

Step 5:
362 divided by 40 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
Subtracting 360 from 362 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 40

Going ahead to step 6:
29 divided by 40 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 6090.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
40 goes into 290 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 6090.7
The remainder is 10 after subtracting 280 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 6090.72
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6090.725
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6090.725
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.

On to step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6090.725
If we subtract 0 from 0, 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.

The quotient of the division is 6090.725, and the remainder is 0.0.
