We're dividing 593692 by 21 
We're looking to find how many times 21 goes into 593692.

Advancing to step 1:
If we divide 5 by 21, we get 0 and 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.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 21

Advancing to step 2:
The number 21 fits into 59 2 times, leaving a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 42 from 59 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 21

Advancing to step 3:
21 can be fit into 173 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 168 away from 173, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

On to step 4:
56 divided by 21 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 282.0
If we take 42 away from 56, we end up with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 21

On to step 5:
149 divided by 21 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2827.0
Subtracting 147 from 149 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

Let's proceed to step 6:
21 can be fit into 22 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 28271.0
Subtracting 21 from 22 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.

Let's proceed to step 7:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 28271.0
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.

Advancing to step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 28271.04
Deduct 84 from 100 and we're left 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.

Going ahead to step 9:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 28271.047
The remainder is 13 after subtracting 147 from 160.
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 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 28271.0476
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.

Advancing to step 11:
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: 28271.04761
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.

Step 12:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 28271.047619
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.

Moving on to step 13:
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: 28271.047619
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.

Step 14:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 28271.04761904
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.

Our division results in 28271.04761904 with a remaining 1.6e-08.
