216721 divided by 48 
Our goal is to divide 216721 by 48.

Advancing to step 1:
48 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 48

Going ahead to step 2:
When dividing 21 by 48, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 48

Going ahead to step 3:
216 divided by 48 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 192 from 216, we get 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 48

Let's proceed to step 4:
If we divide 247 by 48, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 240 from 247 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 48

On to step 5:
When dividing 72 by 48, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 451.0
If we subtract 48 from 72, we get 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 48

Moving on to step 6:
If we divide 241 by 48, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 4515.0
Subtracting 240 from 241 leaves us 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.

Let's proceed to step 7:
10 divided by 48 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4515.0
If we subtract 0 from 10, we 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.

On to step 8:
48 goes into 100 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 4515.02
If we subtract 96 from 100, 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.

Let's proceed to step 9:
The number 48 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4515.02
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
48 can be fit into 400 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 4515.0208
The remainder is 16 after subtracting 384 from 400.
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 11:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 4515.02083
Subtract 144 from 160 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 12:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 4515.020833
Subtract 144 from 160 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.

After the division, we end up with 4515.020833 and a remainder of 1.6e-06.
