450382 divided by 40 
The aim is to understand the frequency of 40 in 450382.

On to step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 40

Advancing to step 2:
The number 40 fits into 45 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
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

Advancing to step 3:
40 goes into 50 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 40 from 50 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 40

Advancing to step 4:
If we divide 103 by 40, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 23 after subtracting 80 from 103.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 40

On to step 5:
The number 40 fits into 238 5 times, leaving a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 1125.0
Subtract 200 from 238 to get 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 40

On to step 6:
If we divide 382 by 40, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 11259.0
Subtracting 360 from 382 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
220 divided by 40 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 11259.5
Deduct 200 from 220 and we're left 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 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11259.55
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.

After the division, we end up with 11259.55 and a remainder of 0.0.
