We look at the division of 63879 by 73 
We're looking to find how many times 73 goes into 63879.

Going ahead to step 1:
If we divide 6 by 73, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 73

Step 2:
73 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 73

Advancing to step 3:
When dividing 638 by 73, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 584 away from 638, we end up with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 73

Moving on to step 4:
73 can be fit into 547 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
The remainder is 36 after subtracting 511 from 547.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 73

Moving on to step 5:
When dividing 369 by 73, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 875.0
If we subtract 365 from 369, we 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.

Let's proceed to step 6:
73 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 875.0
Subtracting 0 from 40 leaves us 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.

On to step 7:
The number 73 fits into 400 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 875.05
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.

Moving on to step 8:
73 can be fit into 350 4 times, resulting in a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 875.054
The remainder is 58 after subtracting 292 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
580 divided by 73 is 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 875.0547
If we subtract 511 from 580, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
73 can be fit into 690 9 times, resulting in a remainder of 33.
The next digit of our result is 9. 
Result so far: 875.05479
Subtract 657 from 690 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
When dividing 330 by 73, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 875.054794
Subtract 292 from 330 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
380 divided by 73 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 875.0547945
If we subtract 365 from 380, we get 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 13:
150 divided by 73 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 875.05479452
Deduct 146 from 150 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 875.05479452 with a remainder of 4e-09.
