3550785 ÷ 743 
We want to divide 3550785 by 743.

Advancing to step 1:
743 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 743

On to step 2:
743 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 743

Moving on to step 3:
If we divide 355 by 743, we get 0 and a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 355 and we're left with 355.
Take the next digit (0) from the dividend and append it to 355, then repeat: 3550 / 743

Step 4:
3550 divided by 743 is 4 with a remainder of 578.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2972 from 3550, we get 578.
Fetch the next digit (7) from the dividend, attach it to 578 and continue: 5787 / 743

Advancing to step 5:
When dividing 5787 by 743, we get 7 with a remainder of 586.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 5201 from 5787 leaves us with 586.
Include the next digit (8) from the dividend after 586, then repeat: 5868 / 743

Moving on to step 6:
5868 divided by 743 is 7 with a remainder of 667.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
The remainder is 667 after subtracting 5201 from 5868.
Bring next digit (5) of the dividend behind the 667 and repeat the process: 6675 / 743

Moving on to step 7:
When dividing 6675 by 743, we get 8 with a remainder of 731.
Record the quotient 8 as the next digit in the result. 
Result so far: 4778.0
If we subtract 5944 from 6675, we get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Let's proceed to step 8:
7310 divided by 743 is 9 with a remainder of 623.
Put 9 as the next digit of the answer. 
Result so far: 4778.9
Subtracting 6687 from 7310 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 9:
When dividing 6230 by 743, we get 8 with a remainder of 286.
The next digit of our result is 8. 
Result so far: 4778.98
The remainder is 286 after subtracting 5944 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
When dividing 2860 by 743, we get 3 with a remainder of 631.
Use 3 as the next digit of our solution. 
Result so far: 4778.983
The remainder is 631 after subtracting 2229 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 11:
If we divide 6310 by 743, we get 8 and a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 4778.9838
Subtract 5944 from 6310 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 12:
The number 743 fits into 3660 4 times, leaving a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 4778.98384
Subtract 2972 from 3660 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 13:
The number 743 fits into 6880 9 times, leaving a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 4778.983849
If we take 6687 away from 6880, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 14:
743 goes into 1930 2 times with a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 4778.9838492
Subtracting 1486 from 1930 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 15:
The number 743 fits into 4440 5 times, leaving a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 4778.98384925
The remainder is 725 after subtracting 3715 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

The final result is 4778.98384925 with a remainder of 7.25e-07.
