1900391 ÷ 514 
Let's see how many times 514 fits into 1900391.

Going ahead to step 1:
514 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 514

Moving on to step 2:
When dividing 19 by 514, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 514

Moving on to step 3:
514 goes into 190 0 times with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 190 to get 190.
Include the next digit (0) from the dividend after 190, then repeat: 1900 / 514

On to step 4:
The number 514 fits into 1900 3 times, leaving a remainder of 358.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 358 after subtracting 1542 from 1900.
Fetch the next digit (3) from the dividend, attach it to 358 and continue: 3583 / 514

Advancing to step 5:
514 goes into 3583 6 times with a remainder of 499.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 3084 away from 3583, we end up with 499.
Take the next digit (9) from the dividend and append it to 499, then repeat: 4999 / 514

Step 6:
514 can be fit into 4999 9 times, resulting in a remainder of 373.
Record the quotient 9 as the next digit in the result. 
Result so far: 369.0
Deduct 4626 from 4999 and we're left with 373.
Include the next digit (1) from the dividend after 373, then repeat: 3731 / 514

Let's proceed to step 7:
514 goes into 3731 7 times with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 3697.0
The remainder is 133 after subtracting 3598 from 3731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 8:
If we divide 1330 by 514, we get 2 and a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 3697.2
The remainder is 302 after subtracting 1028 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
If we divide 3020 by 514, we get 5 and a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 3697.25
The remainder is 450 after subtracting 2570 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
When dividing 4500 by 514, we get 8 with a remainder of 388.
The next digit of our result is 8. 
Result so far: 3697.258
The remainder is 388 after subtracting 4112 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
514 goes into 3880 7 times with a remainder of 282.
Use 7 as the next digit of our solution. 
Result so far: 3697.2587
The remainder is 282 after subtracting 3598 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 12:
If we divide 2820 by 514, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 3697.25875
The remainder is 250 after subtracting 2570 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
When dividing 2500 by 514, we get 4 with a remainder of 444.
The number 4 becomes the next digit in our result. 
Result so far: 3697.258754
The remainder is 444 after subtracting 2056 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 14:
When dividing 4440 by 514, we get 8 with a remainder of 328.
Use 8 as the next digit of our solution. 
Result so far: 3697.2587548
Subtract 4112 from 4440 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 15:
If we divide 3280 by 514, we get 6 and a remainder of 196.
The next digit of our result is 6. 
Result so far: 3697.25875486
If we subtract 3084 from 3280, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 3697.25875486, with a leftover of 1.96e-07.
