Let's divide 63365 by 21
We want to figure out the number of times 63365 can be divided by 21.

Moving on to step 1:
21 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 21

On to step 2:
If we divide 63 by 21, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 63 from 63 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 21

Going ahead to step 3:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 3 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 21

Step 4:
When dividing 36 by 21, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
Subtract 21 from 36 to get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 21

Let's proceed to step 5:
21 goes into 155 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 3017.0
If we subtract 147 from 155, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3017.3
Deduct 63 from 80 and we're left 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.

Let's proceed to step 7:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3017.38
Deduct 168 from 170 and we're left 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.

Moving on to step 8:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3017.38
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 3017.3809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 3017.38095
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.

Step 11:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3017.380952
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.

Let's proceed to step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3017.3809523
Subtracting 63 from 80 leaves us 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.

On to step 13:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 3017.38095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 3017.38095238 and a remainder of 2e-09.
