49948 divided by 21 
We're looking to find how many times 21 goes into 49948.

On to step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

Going ahead to step 2:
21 goes into 49 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 42 away from 49, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 21

Let's proceed to step 3:
If we divide 79 by 21, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 63 from 79 leaves us with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 21

Moving on to step 4:
The number 21 fits into 164 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 237.0
If we subtract 147 from 164, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 21

Step 5:
21 goes into 178 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 2378.0
If we take 168 away from 178, we end up with 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 6:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 2378.4
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.

Advancing to step 7:
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: 2378.47
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.

Going ahead to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 2378.476
Subtract 126 from 130 to 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.

Let's proceed to step 9:
21 goes into 40 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2378.4761
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.

Let's proceed to step 10:
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: 2378.47619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2378.47619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
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: 2378.4761904
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.

Going ahead to step 13:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2378.47619047
Subtracting 147 from 160 leaves us 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.

In conclusion, the division gives 2378.47619047 with a balance of 1.3e-08.
