78483517 ÷ 490 
Let's see how many times 490 fits into 78483517.

Moving on to step 1:
490 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 490

Step 2:
The number 490 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 490

Going ahead to step 3:
When dividing 784 by 490, we get 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 490 away from 784, we end up with 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 490

Step 4:
If we divide 2948 by 490, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 8 after subtracting 2940 from 2948.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 490

Moving on to step 5:
490 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 490

Going ahead to step 6:
The number 490 fits into 835 1 times, leaving a remainder of 345.
Record the quotient 1 as the next digit in the result. 
Result so far: 1601.0
If we take 490 away from 835, we end up with 345.
Bring next digit (1) of the dividend behind the 345 and repeat the process: 3451 / 490

Let's proceed to step 7:
When dividing 3451 by 490, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 16017.0
If we take 3430 away from 3451, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 490

Step 8:
490 goes into 217 0 times with a remainder of 217.
The next digit of our result is 0. 
Result so far: 160170.0
If we subtract 0 from 217, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 9:
When dividing 2170 by 490, we get 4 with a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 160170.4
Subtract 1960 from 2170 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
490 goes into 2100 4 times with a remainder of 140.
The next digit of our result is 4. 
Result so far: 160170.44
The remainder is 140 after subtracting 1960 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 160170.44 with a remainder of 0.14.
