We're dividing 19390137 by 490 
We want to figure out the number of times 19390137 can be divided by 490.

Advancing to step 1:
When dividing 1 by 490, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 490

Advancing to step 2:
If we divide 19 by 490, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 490

Going ahead to step 3:
490 goes into 193 0 times with a remainder of 193.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 193 after subtracting 0 from 193.
Append the next digit (9) from the dividend to 193 and continue with: 1939 / 490

Going ahead to step 4:
490 goes into 1939 3 times with a remainder of 469.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1470 from 1939 and we're left with 469.
Take the next digit (0) from the dividend and append it to 469, then repeat: 4690 / 490

Let's proceed to step 5:
When dividing 4690 by 490, we get 9 with a remainder of 280.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 4410 from 4690 leaves us with 280.
Fetch the next digit (1) from the dividend, attach it to 280 and continue: 2801 / 490

On to step 6:
2801 divided by 490 is 5 with a remainder of 351.
Write down 5 as next digit of the result. 
Result so far: 395.0
The remainder is 351 after subtracting 2450 from 2801.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 490

Let's proceed to step 7:
If we divide 3513 by 490, we get 7 and a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 3957.0
The remainder is 83 after subtracting 3430 from 3513.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 490

Going ahead to step 8:
837 divided by 490 is 1 with a remainder of 347.
Put 1 as the next digit of the answer. 
Result so far: 39571.0
If we take 490 away from 837, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 9:
The number 490 fits into 3470 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 39571.7
If we subtract 3430 from 3470, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 490, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 39571.7
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
4000 divided by 490 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 39571.708
Subtracting 3920 from 4000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 490 is 1 with a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 39571.7081
Subtract 490 from 800 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
490 can be fit into 3100 6 times, resulting in a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 39571.70816
If we take 2940 away from 3100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 490, we get 3 with a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 39571.708163
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 15:
The number 490 fits into 1300 2 times, leaving a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 39571.7081632
Subtract 980 from 1300 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
The number 490 fits into 3200 6 times, leaving a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 39571.70816326
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 39571.70816326, and the remainder is 2.6e-07.
