We look at the division of 66809 by 73 
We want to divide 66809 by 73.

On to step 1:
When dividing 6 by 73, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 73

Moving on to step 2:
If we divide 66 by 73, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 73

Advancing to step 3:
If we divide 668 by 73, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 657 from 668, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 73

Let's proceed to step 4:
110 divided by 73 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Deduct 73 from 110 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 73

Moving on to step 5:
When dividing 379 by 73, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 915.0
Subtract 365 from 379 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.

On to step 6:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 915.1
If we subtract 73 from 140, we get 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 can be fit into 670 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 915.19
Subtracting 657 from 670 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
The number 73 fits into 130 1 times, leaving a remainder of 57.
The next digit of our result is 1. 
Result so far: 915.191
If we take 73 away from 130, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
73 can be fit into 570 7 times, resulting in a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 915.1917
Subtracting 511 from 570 leaves us with 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:
The number 73 fits into 590 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 915.19178
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
When dividing 60 by 73, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 915.19178
If we take 0 away from 60, we end up with 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:
73 goes into 600 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 915.1917808
If we subtract 584 from 600, we 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.

Going ahead to step 13:
160 divided by 73 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 915.19178082
If we subtract 146 from 160, we 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.

Our division results in 915.19178082 with a remaining 1.4e-08.
