Let's divide 450481 by 40
The aim is to understand the frequency of 40 in 450481.

Advancing to step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 40

On to step 2:
40 goes into 45 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 40 away from 45, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 40

Step 3:
When dividing 50 by 40, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 40 away from 50, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 40

Going ahead to step 4:
When dividing 104 by 40, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 80 away from 104, we end up with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 40

Step 5:
248 divided by 40 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1126.0
Subtract 240 from 248 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 40

Moving on to step 6:
When dividing 81 by 40, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 11262.0
Deduct 80 from 81 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 40, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 11262.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 11262.02
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.

On to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11262.025
Subtracting 200 from 200 leaves us 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.

Going ahead to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11262.025
Subtracting 0 from 0 leaves us 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:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11262.025
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.

The final outcome is 11262.025, with a leftover of 0.0.
