We look at the division of 49490 by 21 
We're looking to find how many times 21 goes into 49490.

Moving on to step 1:
4 divided by 21 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

Advancing to step 2:
21 can be fit into 49 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 42 from 49, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Moving on to step 3:
When dividing 74 by 21, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 63 away from 74, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 21

Step 4:
When dividing 119 by 21, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
The remainder is 14 after subtracting 105 from 119.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 21

Step 5:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 2356.0
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 6:
140 divided by 21 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 2356.6
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 21, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2356.66
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 2356.66, and the remainder is 0.014.
