Let's divide 639804 by 73
We're looking to find how many times 73 goes into 639804.

Moving on to step 1:
6 divided by 73 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 73

Going ahead to step 2:
The number 73 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 73

Going ahead to step 3:
The number 73 fits into 639 8 times, leaving a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 55 after subtracting 584 from 639.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 73

Going ahead to step 4:
558 divided by 73 is 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 511 from 558, we get 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 73

Step 5:
If we divide 470 by 73, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 876.0
Subtract 438 from 470 to get 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 73

Going ahead to step 6:
73 can be fit into 324 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 8764.0
The remainder is 32 after subtracting 292 from 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 73 fits into 320 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 8764.4
The remainder is 28 after subtracting 292 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
73 can be fit into 280 3 times, resulting in a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 8764.43
If we subtract 219 from 280, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
73 can be fit into 610 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8764.438
Subtract 584 from 610 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
73 goes into 260 3 times with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 8764.4383
The remainder is 41 after subtracting 219 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
When dividing 410 by 73, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8764.43835
If we subtract 365 from 410, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
73 can be fit into 450 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 8764.438356
If we subtract 438 from 450, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 73, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 8764.4383561
The remainder is 47 after subtracting 73 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
73 goes into 470 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8764.43835616
Deduct 438 from 470 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 8764.43835616 with a balance of 3.2e-08.
