40457801 ÷ 743 
Let's see how many times 743 fits into 40457801.

Step 1:
The number 743 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 743

Step 2:
The number 743 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 743

Moving on to step 3:
743 goes into 404 0 times with a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 404 to get 404.
Include the next digit (5) from the dividend after 404, then repeat: 4045 / 743

Moving on to step 4:
743 can be fit into 4045 5 times, resulting in a remainder of 330.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 330 after subtracting 3715 from 4045.
Append the next digit (7) from the dividend to 330 and continue with: 3307 / 743

On to step 5:
When dividing 3307 by 743, we get 4 with a remainder of 335.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Deduct 2972 from 3307 and we're left with 335.
Include the next digit (8) from the dividend after 335, then repeat: 3358 / 743

Let's proceed to step 6:
743 can be fit into 3358 4 times, resulting in a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
The remainder is 386 after subtracting 2972 from 3358.
Bring next digit (0) of the dividend behind the 386 and repeat the process: 3860 / 743

Step 7:
When dividing 3860 by 743, we get 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 5445.0
Deduct 3715 from 3860 and we're left with 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 743

Let's proceed to step 8:
743 goes into 1451 1 times with a remainder of 708.
The number 1 becomes the next digit in our result. 
Result so far: 54451.0
The remainder is 708 after subtracting 743 from 1451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Let's proceed to step 9:
743 can be fit into 7080 9 times, resulting in a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 54451.9
The remainder is 393 after subtracting 6687 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 10:
743 goes into 3930 5 times with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 54451.95
Subtracting 3715 from 3930 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 11:
2150 divided by 743 is 2 with a remainder of 664.
Record the quotient 2 as the next digit in the result. 
Result so far: 54451.952
Subtracting 1486 from 2150 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 12:
If we divide 6640 by 743, we get 8 and a remainder of 696.
The number 8 becomes the next digit in our result. 
Result so far: 54451.9528
Subtract 5944 from 6640 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 13:
When dividing 6960 by 743, we get 9 with a remainder of 273.
Use 9 as the next digit of our solution. 
Result so far: 54451.95289
Subtract 6687 from 6960 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 14:
2730 divided by 743 is 3 with a remainder of 501.
Record the quotient 3 as the next digit in the result. 
Result so far: 54451.952893
Subtracting 2229 from 2730 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 15:
743 goes into 5010 6 times with a remainder of 552.
Record the quotient 6 as the next digit in the result. 
Result so far: 54451.9528936
Deduct 4458 from 5010 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 16:
If we divide 5520 by 743, we get 7 and a remainder of 319.
Write down 7 as next digit of the result. 
Result so far: 54451.95289367
If we take 5201 away from 5520, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The final result is 54451.95289367 with a remainder of 3.19e-07.
