324757 divided by 21 
We want to figure out the number of times 324757 can be divided by 21.

Let's proceed to step 1:
3 divided by 21 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

Moving on to step 2:
21 goes into 32 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 21 from 32 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 21

Let's proceed to step 3:
If we divide 114 by 21, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 105 from 114 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 21

Moving on to step 4:
If we divide 97 by 21, we get 4 and a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtract 84 from 97 to get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 21

Going ahead to step 5:
21 can be fit into 135 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
Subtracting 126 from 135 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 21

Advancing to step 6:
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: 15464.0
Subtract 84 from 97 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 15464.6
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 8:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 15464.61
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15464.619
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 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15464.619
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.

Going ahead to step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 15464.61904
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 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 15464.619047
If we take 147 away from 160, we end up 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.

Moving on to step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15464.6190476
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.

Moving on to step 14:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 15464.61904761
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.

The final result is 15464.61904761 with a remainder of 1.9e-08.
