We're dividing 502618 by 21 
Our goal is to divide 502618 by 21.

Let's proceed to step 1:
5 divided by 21 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 21

Going ahead to step 2:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 42 from 50 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

Let's proceed to step 3:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 63 from 82, we get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 21

Advancing to step 4:
21 can be fit into 196 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 239.0
The remainder is 7 after subtracting 189 from 196.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 21

Step 5:
If we divide 71 by 21, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 2393.0
If we subtract 63 from 71, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 21

Going ahead to step 6:
88 divided by 21 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 23934.0
Subtracting 84 from 88 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 23934.1
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 23934.19
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23934.19
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 23934.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 23934.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 23934.190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 23934.1904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 23934.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 23934.19047619 with a balance of 1e-09.
