Let's divide 528331 by 21
Let's see how many times 21 fits into 528331.

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
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 21

On to step 2:
The number 21 fits into 52 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 52, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 21

Moving on to step 3:
The number 21 fits into 108 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 105 from 108 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 21

Step 4:
When dividing 33 by 21, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 251.0
Subtract 21 from 33 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 21

Advancing to step 5:
21 goes into 123 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 2515.0
Deduct 105 from 123 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 21

Moving on to step 6:
21 can be fit into 181 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 25158.0
Subtract 168 from 181 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.

Let's proceed to step 7:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 25158.6
The remainder is 4 after subtracting 126 from 130.
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 8:
21 goes into 40 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 25158.61
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 25158.619
Deduct 189 from 190 and we're left 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.

Moving on to step 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25158.619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 25158.61904
If we take 84 away from 100, we end up 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.

Let's proceed to step 12:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 25158.619047
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.

Moving on to step 13:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 25158.6190476
If we take 126 away from 130, we end up 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.

Step 14:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 25158.61904761
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.

The final result is 25158.61904761 with a remainder of 1.9e-08.
