Let's divide 246304 by 21
We want to figure out the number of times 246304 can be divided by 21.

Moving on to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 21

Step 2:
When dividing 24 by 21, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 24, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 21

Step 3:
If we divide 36 by 21, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 15 after subtracting 21 from 36.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 21

Moving on to step 4:
21 can be fit into 153 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 147 from 153, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 21

Let's proceed to step 5:
When dividing 60 by 21, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
If we subtract 42 from 60, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 21

Step 6:
If we divide 184 by 21, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 11728.0
Subtracting 168 from 184 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.

Moving on to step 7:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 11728.7
Subtract 147 from 160 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.

On to step 8:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 11728.76
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.

Going ahead to step 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 11728.761
If we take 21 away from 40, we end up 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.

Going ahead to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 11728.7619
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.

Step 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11728.7619
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.

Moving on to step 12:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11728.761904
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 13:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 11728.7619047
Subtract 147 from 160 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.

Step 14:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11728.76190476
If we take 126 away from 130, we end up 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.

The final result is 11728.76190476 with a remainder of 4e-09.
