Let's divide 592831 by 21
Let's see how many times 21 fits into 592831.

Step 1:
21 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 21

Step 2:
21 can be fit into 59 2 times, resulting in a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 42 from 59 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 21

Let's proceed to step 3:
If we divide 172 by 21, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 168 from 172 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

Going ahead to step 4:
If we divide 48 by 21, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 282.0
The remainder is 6 after subtracting 42 from 48.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 21

On to step 5:
The number 21 fits into 63 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 2823.0
Subtracting 63 from 63 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 21

Advancing to step 6:
1 divided by 21 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 28230.0
Subtracting 0 from 1 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.

Going ahead to step 7:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 28230.0
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.

Advancing to step 8:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 28230.04
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 28230.047
Deduct 147 from 160 and we're left with 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 10:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 28230.0476
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.

Let's proceed to step 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 28230.04761
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 12:
21 goes into 190 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 28230.047619
If we subtract 189 from 190, we get 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 13:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 28230.047619
Subtracting 0 from 10 leaves us 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 14:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 28230.04761904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 28230.04761904 and a remainder of 1.6e-08.
