We look at the division of 593093 by 21 
We want to divide 593093 by 21.

Let's proceed to step 1:
21 can be fit into 5 0 times, resulting in 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.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Going ahead to step 2:
59 divided by 21 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 42 from 59, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 21

Moving on to step 3:
173 divided by 21 is 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 168 from 173 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 21

Let's proceed to step 4:
If we divide 50 by 21, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 282.0
If we subtract 42 from 50, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 21

Let's proceed to step 5:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 2824.0
If we subtract 84 from 89, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 21

Advancing to step 6:
21 can be fit into 53 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 28242.0
Deduct 42 from 53 and we're left 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.

Going ahead to step 7:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 28242.5
If we subtract 105 from 110, we 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 8:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 28242.52
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 28242.523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 28242.5238
Deduct 168 from 170 and we're left 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 11:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 28242.5238
Subtracting 0 from 20 leaves us 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 12:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 28242.523809
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 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 28242.5238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
21 goes into 50 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 28242.52380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 28242.52380952 with a remainder of 8e-09.
