50529290 divided by 21 
Let's see how many times 21 fits into 50529290.

Going ahead to step 1:
5 divided by 21 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 21

On to step 2:
If we divide 50 by 21, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 50, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 21

Step 3:
21 goes into 85 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 84 from 85 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 21

Step 4:
12 divided by 21 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 240.0
Subtract 0 from 12 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 21

On to step 5:
If we divide 129 by 21, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 2406.0
Subtracting 126 from 129 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

Moving on to step 6:
21 goes into 32 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 24061.0
Subtracting 21 from 32 leaves us with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 21

On to step 7:
If we divide 119 by 21, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 240615.0
The remainder is 14 after subtracting 105 from 119.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

Advancing to step 8:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 2406156.0
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.

Step 9:
140 divided by 21 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 2406156.6
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2406156.66
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.

The final result is 2406156.66 with a remainder of 0.014.
