We're dividing 455238 by 40 
The aim is to understand the frequency of 40 in 455238.

Let's proceed to step 1:
40 can be fit into 4 0 times, resulting in 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.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 40

Step 2:
40 goes into 45 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 40 away from 45, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 40

Moving on to step 3:
40 can be fit into 55 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 40 from 55, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 40

Going ahead to step 4:
152 divided by 40 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtracting 120 from 152 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 40

Let's proceed to step 5:
The number 40 fits into 323 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 1138.0
Deduct 320 from 323 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 40

Going ahead to step 6:
If we divide 38 by 40, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 11380.0
If we take 0 away from 38, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
When dividing 380 by 40, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 11380.9
Subtracting 360 from 380 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.

Moving on to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11380.95
Subtract 200 from 200 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 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11380.95
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.

On to step 10:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11380.95
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.

Our division results in 11380.95 with a remaining 0.0.
