Let's divide 48863 by 21
We want to figure out the number of times 48863 can be divided by 21.

Let's proceed to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 21

On to step 2:
48 divided by 21 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 48 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 21

Going ahead to step 3:
21 goes into 68 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 63 from 68 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Going ahead to step 4:
21 can be fit into 56 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 232.0
If we subtract 42 from 56, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 21

Moving on to step 5:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 2326.0
The remainder is 17 after subtracting 126 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 6:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2326.8
Subtracting 168 from 170 leaves us 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.

Going ahead to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2326.8
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 8:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2326.809
Deduct 189 from 200 and we're left 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.

Let's proceed to step 9:
If we divide 110 by 21, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 2326.8095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
If we divide 50 by 21, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2326.80952
Subtracting 42 from 50 leaves us 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.

Advancing to step 11:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 2326.809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 2326.8095238
Subtracting 168 from 170 leaves us 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.

Advancing to step 13:
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: 2326.8095238
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.

After the division, we end up with 2326.8095238 and a remainder of 2e-08.
