506974 divided by 21 
We want to divide 506974 by 21.

On to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our 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

Step 2:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 50 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 21

Advancing to step 3:
86 divided by 21 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 84 from 86, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 21

Let's proceed to step 4:
29 divided by 21 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
The remainder is 8 after subtracting 21 from 29.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 21

On to step 5:
If we divide 87 by 21, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 2414.0
If we subtract 84 from 87, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 21

On to step 6:
The number 21 fits into 34 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 24141.0
If we subtract 21 from 34, 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 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 24141.6
Deduct 126 from 130 and we're left 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.

Moving on to step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 24141.61
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 24141.619
If we take 189 away from 190, we end up 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.

Advancing to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 24141.619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 24141.61904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 24141.619047
Subtract 147 from 160 to 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.

Step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 24141.6190476
Subtracting 126 from 130 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.

On to step 14:
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: 24141.61904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 24141.61904761, and the remainder is 1.9e-08.
