16391 ÷ 73 
Our goal is to divide 16391 by 73.

Step 1:
1 divided by 73 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 73

Step 2:
73 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 73

Let's proceed to step 3:
The number 73 fits into 163 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 146 from 163 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 73

On to step 4:
73 goes into 179 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 146 from 179 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 73

Let's proceed to step 5:
When dividing 331 by 73, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
If we subtract 292 from 331, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 6:
The number 73 fits into 390 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 224.5
Subtracting 365 from 390 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
The number 73 fits into 250 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 224.53
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
When dividing 310 by 73, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 224.534
If we take 292 away from 310, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
If we divide 180 by 73, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 224.5342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
73 can be fit into 340 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 224.53424
If we take 292 away from 340, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 73 is 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 224.534246
Subtract 438 from 480 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
73 can be fit into 420 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 224.5342465
If we subtract 365 from 420, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
The number 73 fits into 550 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 224.53424657
If we take 511 away from 550, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 224.53424657 with a remainder of 3.9e-08.
