320488 ÷ 73 
Let's see how many times 73 fits into 320488.

Advancing to step 1:
73 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 73

Advancing to step 2:
The number 73 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 73

Step 3:
73 can be fit into 320 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 292 from 320, we get 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 73

Going ahead to step 4:
When dividing 284 by 73, we get 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 219 from 284 to get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 73

Going ahead to step 5:
73 goes into 658 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
If we subtract 657 from 658, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 73

Going ahead to step 6:
When dividing 18 by 73, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 4390.0
Deduct 0 from 18 and we're left 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.

Advancing to step 7:
73 goes into 180 2 times with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 4390.2
Subtract 146 from 180 to get 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 8:
73 can be fit into 340 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4390.24
Subtracting 292 from 340 leaves us 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.

Advancing to step 9:
The number 73 fits into 480 6 times, leaving a remainder of 42.
The next digit of our result is 6. 
Result so far: 4390.246
The remainder is 42 after subtracting 438 from 480.
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 10:
420 divided by 73 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 4390.2465
Subtracting 365 from 420 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
73 goes into 550 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 4390.24657
The remainder is 39 after subtracting 511 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
If we divide 390 by 73, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4390.246575
Subtract 365 from 390 to get 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 13:
When dividing 250 by 73, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 4390.2465753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
The number 73 fits into 310 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4390.24657534
Subtracting 292 from 310 leaves us 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.

Our division results in 4390.24657534 with a remaining 1.8e-08.
