3762443 divided by 721 
Let's see how many times 721 fits into 3762443.

Going ahead to step 1:
721 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 721

Moving on to step 2:
37 divided by 721 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 721

On to step 3:
721 goes into 376 0 times with a remainder of 376.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 376 after subtracting 0 from 376.
Bring next digit (2) of the dividend behind the 376 and repeat the process: 3762 / 721

Moving on to step 4:
721 can be fit into 3762 5 times, resulting in a remainder of 157.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3605 from 3762 and we're left with 157.
Include the next digit (4) from the dividend after 157, then repeat: 1574 / 721

Advancing to step 5:
721 goes into 1574 2 times with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 1442 away from 1574, we end up with 132.
Include the next digit (4) from the dividend after 132, then repeat: 1324 / 721

Step 6:
If we divide 1324 by 721, we get 1 and a remainder of 603.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtracting 721 from 1324 leaves us with 603.
Fetch the next digit (3) from the dividend, attach it to 603 and continue: 6033 / 721

Step 7:
When dividing 6033 by 721, we get 8 with a remainder of 265.
The number 8 becomes the next digit in our result. 
Result so far: 5218.0
Deduct 5768 from 6033 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 8:
The number 721 fits into 2650 3 times, leaving a remainder of 487.
Record the quotient 3 as the next digit in the result. 
Result so far: 5218.3
Subtracting 2163 from 2650 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 9:
721 goes into 4870 6 times with a remainder of 544.
Put 6 as the next digit of the answer. 
Result so far: 5218.36
Subtracting 4326 from 4870 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 10:
When dividing 5440 by 721, we get 7 with a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 5218.367
If we subtract 5047 from 5440, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 11:
721 can be fit into 3930 5 times, resulting in a remainder of 325.
The next digit of our result is 5. 
Result so far: 5218.3675
If we subtract 3605 from 3930, 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.

On to step 12:
The number 721 fits into 3250 4 times, leaving a remainder of 366.
The next digit of our result is 4. 
Result so far: 5218.36754
If we take 2884 away from 3250, we end up with 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 13:
721 can be fit into 3660 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5218.367545
If we take 3605 away from 3660, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
550 divided by 721 is 0 with a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 5218.367545
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 15:
If we divide 5500 by 721, we get 7 and a remainder of 453.
The number 7 becomes the next digit in our result. 
Result so far: 5218.36754507
Deduct 5047 from 5500 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

The final outcome is 5218.36754507, with a leftover of 4.53e-07.
