Let's divide 935921 by 40
The aim is to understand the frequency of 40 in 935921.

Going ahead to step 1:
When dividing 9 by 40, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 40

On to step 2:
40 goes into 93 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 80 from 93 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 40

Let's proceed to step 3:
When dividing 135 by 40, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 120 from 135 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 40

Step 4:
If we divide 159 by 40, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 233.0
The remainder is 39 after subtracting 120 from 159.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 40

Step 5:
When dividing 392 by 40, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 2339.0
Subtract 360 from 392 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 40

Going ahead to step 6:
When dividing 321 by 40, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 23398.0
The remainder is 1 after subtracting 320 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 40 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23398.0
Deduct 0 from 10 and we're left with 10.
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:
100 divided by 40 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 23398.02
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.

Let's proceed to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 23398.025
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.

Let's proceed to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23398.025
Subtract 0 from 0 to 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.

On to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23398.025
If we take 0 away from 0, we end up 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.

After the division, we end up with 23398.025 and a remainder of 0.0.
