743 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 743

Advancing to step 2:
21 divided by 743 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 743

When dividing 213 by 743, we get 0 with a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Fetch the next digit (8) from the dividend, attach it to 213 and continue: 2138 / 743

On to step 4:
743 goes into 2138 2 times with a remainder of 652.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 652 after subtracting 1486 from 2138.
Append the next digit (9) from the dividend to 652 and continue with: 6529 / 743

Advancing to step 5:
If we divide 6529 by 743, we get 8 and a remainder of 585.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 5944 from 6529, we get 585.
Include the next digit (2) from the dividend after 585, then repeat: 5852 / 743

Advancing to step 6:
When dividing 5852 by 743, we get 7 with a remainder of 651.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtracting 5201 from 5852 leaves us with 651.
Fetch the next digit (8) from the dividend, attach it to 651 and continue: 6518 / 743

Advancing to step 7:
743 can be fit into 6518 8 times, resulting in a remainder of 574.
The number 8 becomes the next digit in our result. 
Result so far: 2878.0
Subtract 5944 from 6518 to get 574.
Fetch the next digit (0) from the dividend, attach it to 574 and continue: 5740 / 743

Advancing to step 8:
If we divide 5740 by 743, we get 7 and a remainder of 539.
The next digit of our result is 7. 
Result so far: 28787.0
Subtract 5201 from 5740 to get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 9:
743 can be fit into 5390 7 times, resulting in a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 28787.7
Subtract 5201 from 5390 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 10:
The number 743 fits into 1890 2 times, leaving a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 28787.72
Deduct 1486 from 1890 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 11:
743 goes into 4040 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 28787.725
If we subtract 3715 from 4040, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 12:
743 can be fit into 3250 4 times, resulting in a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 28787.7254
Subtracting 2972 from 3250 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 13:
When dividing 2780 by 743, we get 3 with a remainder of 551.
The number 3 becomes the next digit in our result. 
Result so far: 28787.72543
If we subtract 2229 from 2780, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

On to step 14:
The number 743 fits into 5510 7 times, leaving a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 28787.725437
Deduct 5201 from 5510 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 15:
When dividing 3090 by 743, we get 4 with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 28787.7254374
If we take 2972 away from 3090, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 16:
If we divide 1180 by 743, we get 1 and a remainder of 437.
The number 1 becomes the next digit in our result. 
Result so far: 28787.72543741
Subtract 743 from 1180 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

In conclusion, the division gives 28787.72543741 with a balance of 4.37e-07.
