19890070 divided by 490 
We want to divide 19890070 by 490.

Advancing to step 1:
The number 490 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 490

Let's proceed to step 2:
490 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 490

Advancing to step 3:
490 can be fit into 198 0 times, resulting in a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 198 leaves us with 198.
Take the next digit (9) from the dividend and append it to 198, then repeat: 1989 / 490

Advancing to step 4:
If we divide 1989 by 490, we get 4 and a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1960 from 1989 leaves us with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 490

On to step 5:
When dividing 290 by 490, we get 0 with a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 290 after subtracting 0 from 290.
Grab the next digit (0) from the dividend, add it to 290, then carry on: 2900 / 490

Moving on to step 6:
490 can be fit into 2900 5 times, resulting in a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtract 2450 from 2900 to get 450.
Grab the next digit (7) from the dividend, add it to 450, then carry on: 4507 / 490

Going ahead to step 7:
The number 490 fits into 4507 9 times, leaving a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 4059.0
If we take 4410 away from 4507, we end up with 97.
Bring next digit (0) of the dividend behind the 97 and repeat the process: 970 / 490

Going ahead to step 8:
The number 490 fits into 970 1 times, leaving a remainder of 480.
The next digit of our result is 1. 
Result so far: 40591.0
If we take 490 away from 970, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 9:
The number 490 fits into 4800 9 times, leaving a remainder of 390.
Use 9 as the next digit of our solution. 
Result so far: 40591.9
The remainder is 390 after subtracting 4410 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
490 can be fit into 3900 7 times, resulting in a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 40591.97
Subtract 3430 from 3900 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 11:
When dividing 4700 by 490, we get 9 with a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 40591.979
Deduct 4410 from 4700 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 12:
The number 490 fits into 2900 5 times, leaving a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 40591.9795
If we take 2450 away from 2900, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 13:
If we divide 4500 by 490, we get 9 and a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 40591.97959
Subtracting 4410 from 4500 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
If we divide 900 by 490, we get 1 and a remainder of 410.
The next digit of our result is 1. 
Result so far: 40591.979591
Subtracting 490 from 900 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 15:
If we divide 4100 by 490, we get 8 and a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 40591.9795918
If we subtract 3920 from 4100, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 16:
The number 490 fits into 1800 3 times, leaving a remainder of 330.
The next digit of our result is 3. 
Result so far: 40591.97959183
Deduct 1470 from 1800 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The quotient of the division is 40591.97959183, and the remainder is 3.3e-07.
