We divide 48988 by 21
Let's see how many times 21 fits into 48988.

Moving on to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 21

On to step 2:
21 goes into 48 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 48 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

On to step 3:
The number 21 fits into 69 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 63 from 69 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 21

Advancing to step 4:
The number 21 fits into 68 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 233.0
Subtracting 63 from 68 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

On to step 5:
When dividing 58 by 21, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2332.0
Deduct 42 from 58 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.

On to step 6:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 2332.7
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.

Going ahead to step 7:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2332.76
Subtracting 126 from 130 leaves us 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.

Step 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2332.761
Deduct 21 from 40 and we're left 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.

Let's proceed to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 2332.7619
Subtract 189 from 190 to 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 10:
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: 2332.7619
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.

Step 11:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2332.761904
If we subtract 84 from 100, we 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.

On to step 12:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2332.7619047
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.

Moving on to step 13:
When dividing 130 by 21, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2332.76190476
Deduct 126 from 130 and we're left 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.

After the division, we end up with 2332.76190476 and a remainder of 4e-09.
