597742 divided by 21 
We want to divide 597742 by 21.

Going ahead to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our 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

Step 2:
If we divide 59 by 21, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 42 away from 59, we end up with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 21

Advancing to step 3:
If we divide 177 by 21, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 168 from 177 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 21

Going ahead to step 4:
21 can be fit into 97 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 284.0
If we take 84 away from 97, we end up with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 21

Moving on to step 5:
If we divide 134 by 21, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 2846.0
Subtract 126 from 134 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 21

Moving on to step 6:
21 can be fit into 82 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 28463.0
Subtracting 63 from 82 leaves us 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.

Step 7:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 28463.9
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.

Step 8:
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: 28463.9
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.

Moving on to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 28463.904
Subtract 84 from 100 to 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.

Let's proceed to step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 28463.9047
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.

Moving on to step 11:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 28463.90476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 28463.904761
Subtracting 21 from 40 leaves us 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.

Step 13:
If we divide 190 by 21, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 28463.9047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 28463.9047619
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.

The quotient of the division is 28463.9047619, and the remainder is 1e-08.
