16521 ÷ 73 
Our goal is to divide 16521 by 73.

Step 1:
73 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 73

Moving on to step 2:
73 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 73

Let's proceed to step 3:
If we divide 165 by 73, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 146 from 165 to get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 73

Moving on to step 4:
73 can be fit into 192 2 times, resulting in a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 146 away from 192, we end up with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 73

Let's proceed to step 5:
73 can be fit into 461 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Deduct 438 from 461 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 6:
If we divide 230 by 73, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 226.3
Subtracting 219 from 230 leaves us 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.

On to step 7:
When dividing 110 by 73, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 226.31
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 73, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 226.315
If we take 365 away from 370, 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 9:
When dividing 50 by 73, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 226.315
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 73, we get 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 226.31506
Subtracting 438 from 500 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
When dividing 620 by 73, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 226.315068
Subtracting 584 from 620 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
360 divided by 73 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 226.3150684
Subtracting 292 from 360 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
The number 73 fits into 680 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 226.31506849
Subtract 657 from 680 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 226.31506849 with a remainder of 2.3e-08.
