80381213 ÷ 743 
Our goal is to divide 80381213 by 743.

Going ahead to step 1:
When dividing 8 by 743, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 743

On to step 2:
80 divided by 743 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 743

Step 3:
The number 743 fits into 803 1 times, leaving a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 743 from 803 leaves us with 60.
Include the next digit (8) from the dividend after 60, then repeat: 608 / 743

Moving on to step 4:
If we divide 608 by 743, we get 0 and a remainder of 608.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 608 leaves us with 608.
Include the next digit (1) from the dividend after 608, then repeat: 6081 / 743

Let's proceed to step 5:
6081 divided by 743 is 8 with a remainder of 137.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 5944 from 6081 to get 137.
Append the next digit (2) from the dividend to 137 and continue with: 1372 / 743

Advancing to step 6:
If we divide 1372 by 743, we get 1 and a remainder of 629.
Write down 1 as next digit of the result. 
Result so far: 1081.0
The remainder is 629 after subtracting 743 from 1372.
Grab the next digit (1) from the dividend, add it to 629, then carry on: 6291 / 743

On to step 7:
If we divide 6291 by 743, we get 8 and a remainder of 347.
Put 8 as the next digit of the answer. 
Result so far: 10818.0
Subtracting 5944 from 6291 leaves us with 347.
Include the next digit (3) from the dividend after 347, then repeat: 3473 / 743

Going ahead to step 8:
The number 743 fits into 3473 4 times, leaving a remainder of 501.
The next digit of our result is 4. 
Result so far: 108184.0
Subtract 2972 from 3473 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 9:
If we divide 5010 by 743, we get 6 and a remainder of 552.
Record the quotient 6 as the next digit in the result. 
Result so far: 108184.6
Subtracting 4458 from 5010 leaves us 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.

Moving on to step 10:
743 goes into 5520 7 times with a remainder of 319.
Write down 7 as next digit of the result. 
Result so far: 108184.67
The remainder is 319 after subtracting 5201 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 11:
If we divide 3190 by 743, we get 4 and a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 108184.674
Subtracting 2972 from 3190 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 12:
743 goes into 2180 2 times with a remainder of 694.
Write down 2 as next digit of the result. 
Result so far: 108184.6742
Deduct 1486 from 2180 and we're left with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Moving on to step 13:
743 can be fit into 6940 9 times, resulting in a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 108184.67429
If we subtract 6687 from 6940, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 14:
743 can be fit into 2530 3 times, resulting in a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 108184.674293
Subtracting 2229 from 2530 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 15:
The number 743 fits into 3010 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 108184.6742934
Deduct 2972 from 3010 and we're left 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.

Let's proceed to step 16:
If we divide 380 by 743, we get 0 and a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 108184.6742934
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 108184.6742934 with a remainder of 3.8e-07.
