We're dividing 505535 by 21 
Let's see how many times 21 fits into 505535.

Advancing to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 21

Step 2:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 42 from 50 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 21

Let's proceed to step 3:
85 divided by 21 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 1 after subtracting 84 from 85.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 21

On to step 4:
If we divide 15 by 21, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 240.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 21

On to step 5:
21 goes into 153 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2407.0
The remainder is 6 after subtracting 147 from 153.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 21

Moving on to step 6:
21 goes into 65 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 24073.0
If we take 63 away from 65, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 24073.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 24073.09
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 24073.095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 24073.0952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 24073.09523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 24073.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 24073.095238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 24073.09523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 24073.09523809, and the remainder is 1.1e-08.
