1782373 ÷ 391 
We want to divide 1782373 by 391.

Step 1:
The number 391 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 391

Step 2:
If we divide 17 by 391, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 391

Advancing to step 3:
391 goes into 178 0 times with a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 178, we end up with 178.
Bring next digit (2) of the dividend behind the 178 and repeat the process: 1782 / 391

Step 4:
1782 divided by 391 is 4 with a remainder of 218.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1564 away from 1782, we end up with 218.
Bring next digit (3) of the dividend behind the 218 and repeat the process: 2183 / 391

On to step 5:
391 can be fit into 2183 5 times, resulting in a remainder of 228.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 1955 from 2183 to get 228.
Append the next digit (7) from the dividend to 228 and continue with: 2287 / 391

Step 6:
When dividing 2287 by 391, we get 5 with a remainder of 332.
Put 5 as the next digit of the answer. 
Result so far: 455.0
Subtracting 1955 from 2287 leaves us with 332.
Include the next digit (3) from the dividend after 332, then repeat: 3323 / 391

Going ahead to step 7:
When dividing 3323 by 391, we get 8 with a remainder of 195.
The next digit of our result is 8. 
Result so far: 4558.0
Deduct 3128 from 3323 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 8:
391 can be fit into 1950 4 times, resulting in a remainder of 386.
The next digit of our result is 4. 
Result so far: 4558.4
The remainder is 386 after subtracting 1564 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
When dividing 3860 by 391, we get 9 with a remainder of 341.
Put 9 as the next digit of the answer. 
Result so far: 4558.49
If we take 3519 away from 3860, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 10:
The number 391 fits into 3410 8 times, leaving a remainder of 282.
Record the quotient 8 as the next digit in the result. 
Result so far: 4558.498
Subtract 3128 from 3410 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 11:
If we divide 2820 by 391, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 4558.4987
Deduct 2737 from 2820 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
830 divided by 391 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 4558.49872
If we take 782 away from 830, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 391, we get 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 4558.498721
If we subtract 391 from 480, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 14:
When dividing 890 by 391, we get 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 4558.4987212
The remainder is 108 after subtracting 782 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 15:
391 can be fit into 1080 2 times, resulting in a remainder of 298.
Put 2 as the next digit of the answer. 
Result so far: 4558.49872122
Subtracting 782 from 1080 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The final outcome is 4558.49872122, with a leftover of 2.98e-07.
