We look at the division of 638817 by 73 
We're looking to find how many times 73 goes into 638817.

Moving on to step 1:
When dividing 6 by 73, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 73

Step 2:
63 divided by 73 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 73

Moving on to step 3:
The number 73 fits into 638 8 times, leaving a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 584 from 638 leaves us with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 73

Step 4:
73 can be fit into 548 7 times, resulting in a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 37 after subtracting 511 from 548.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 73

On to step 5:
The number 73 fits into 371 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 875.0
If we subtract 365 from 371, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 73

Step 6:
The number 73 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 8750.0
Subtracting 0 from 67 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
73 goes into 670 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 8750.9
The remainder is 13 after subtracting 657 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
73 can be fit into 130 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 8750.91
If we subtract 73 from 130, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
If we divide 570 by 73, we get 7 and a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 8750.917
Subtract 511 from 570 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
73 goes into 590 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8750.9178
The remainder is 6 after subtracting 584 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
73 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8750.9178
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 73 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8750.917808
Subtract 584 from 600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
73 can be fit into 160 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 8750.9178082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
If we divide 140 by 73, we get 1 and a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 8750.91780821
Deduct 73 from 140 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 8750.91780821, and the remainder is 6.7e-08.
