596768 ÷ 21 
Our goal is to divide 596768 by 21.

Going ahead to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 21

Let's proceed to step 2:
If we divide 59 by 21, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 17 after subtracting 42 from 59.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 21

On to step 3:
21 goes into 176 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 168 from 176 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 21

Advancing to step 4:
The number 21 fits into 87 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 284.0
If we subtract 84 from 87, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

Advancing to step 5:
21 goes into 36 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 2841.0
If we take 21 away from 36, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 21

On to step 6:
The number 21 fits into 158 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 28417.0
If we take 147 away from 158, we end up 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.

Advancing to step 7:
When dividing 110 by 21, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 28417.5
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.

Advancing to step 8:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 28417.52
Deduct 42 from 50 and we're left with 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:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 28417.523
If we take 63 away from 80, we end up 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.

Step 10:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28417.5238
If we take 168 away from 170, we end up 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.

On to step 11:
21 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 28417.5238
Deduct 0 from 20 and we're left 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.

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: 28417.523809
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.

Advancing to step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 28417.5238095
Subtract 105 from 110 to 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 14:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 28417.52380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 28417.52380952 with a balance of 8e-09.
