We're dividing 809573 by 73 
We want to figure out the number of times 809573 can be divided by 73.

Going ahead to step 1:
73 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 73

Going ahead to step 2:
The number 73 fits into 80 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 73 from 80 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 73

Moving on to step 3:
If we divide 79 by 73, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 11.0
If we take 73 away from 79, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 73

Advancing to step 4:
If we divide 65 by 73, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 73

Moving on to step 5:
73 can be fit into 657 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 1109.0
Deduct 657 from 657 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 73

Moving on to step 6:
The number 73 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 11090.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 73, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11090.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 73 fits into 300 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 11090.04
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 73 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 11090.041
If we take 73 away from 80, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 73, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 11090.041
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
700 divided by 73 is 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 11090.04109
Subtract 657 from 700 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
If we divide 430 by 73, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 11090.041095
Subtract 365 from 430 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
73 goes into 650 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 11090.0410958
Subtract 584 from 650 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
73 can be fit into 660 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 11090.04109589
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 11090.04109589, and the remainder is 3e-09.
