We look at the division of 639922 by 73 
We want to divide 639922 by 73.

Going ahead to step 1:
If we divide 6 by 73, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 73

Going ahead to step 2:
73 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 73

Going ahead to step 3:
If we divide 639 by 73, we get 8 and a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 584 from 639 and we're left with 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 73

Advancing to step 4:
If we divide 559 by 73, we get 7 and a remainder of 48.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 511 from 559 and we're left with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 73

Let's proceed to step 5:
482 divided by 73 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 876.0
The remainder is 44 after subtracting 438 from 482.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 73

Let's proceed to step 6:
442 divided by 73 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 8766.0
Subtract 438 from 442 to 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.

On to step 7:
40 divided by 73 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8766.0
Deduct 0 from 40 and we're left 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.

Step 8:
If we divide 400 by 73, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8766.05
Subtracting 365 from 400 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
73 can be fit into 350 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 8766.054
If we subtract 292 from 350, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
If we divide 580 by 73, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 8766.0547
If we take 511 away from 580, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
73 can be fit into 690 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 8766.05479
Deduct 657 from 690 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
330 divided by 73 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 8766.054794
The remainder is 38 after subtracting 292 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 73, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8766.0547945
Subtracting 365 from 380 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
73 can be fit into 150 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 8766.05479452
The remainder is 4 after subtracting 146 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 8766.05479452 with a balance of 4e-09.
