We divide 14243 by 40
We want to figure out the number of times 14243 can be divided by 40.

Step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 40

Advancing to step 2:
When dividing 14 by 40, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 40

Advancing to step 3:
40 can be fit into 142 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 120 away from 142, we end up with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 40

Step 4:
40 can be fit into 224 5 times, resulting in a remainder of 24.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 24 after subtracting 200 from 224.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 40

Let's proceed to step 5:
40 can be fit into 243 6 times, resulting in a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 356.0
Subtract 240 from 243 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
The number 40 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 356.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
40 goes into 300 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 356.07
Subtracting 280 from 300 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 8:
200 divided by 40 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 356.075
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.

On to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 356.075
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.

Advancing to step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 356.075
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 quotient of the division is 356.075, and the remainder is 0.0.
