451441 ÷ 40 
Let's see how many times 40 fits into 451441.

Advancing 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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Advancing to step 2:
40 can be fit into 45 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 40 from 45 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 40

Advancing to step 3:
40 goes into 51 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 40 from 51 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 40

Advancing to step 4:
114 divided by 40 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtracting 80 from 114 leaves us with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 40

Moving on to step 5:
40 can be fit into 344 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 1128.0
If we take 320 away from 344, we end up with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 40

Let's proceed to step 6:
40 can be fit into 241 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 11286.0
The remainder is 1 after subtracting 240 from 241.
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:
If we divide 10 by 40, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11286.0
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.

Going ahead to step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 11286.02
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:
200 divided by 40 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 11286.025
Deduct 200 from 200 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.

Going ahead to step 10:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11286.025
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11286.025
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.

After the division, we end up with 11286.025 and a remainder of 0.0.
