We look at the division of 803512 by 73 
We want to figure out the number of times 803512 can be divided by 73.

Going ahead to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 73

Let's proceed to step 2:
If we divide 80 by 73, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 73 from 80 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 73

Step 3:
73 can be fit into 73 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 73 from 73 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 73

Let's proceed to step 4:
73 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 73

Moving on to step 5:
The number 73 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 1100.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 73

On to step 6:
512 divided by 73 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11007.0
Deduct 511 from 512 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
73 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11007.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 11007.01
Subtract 73 from 100 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
If we divide 270 by 73, we get 3 and a remainder of 51.
The next digit of our result is 3. 
Result so far: 11007.013
If we take 219 away from 270, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
When dividing 510 by 73, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 11007.0136
Subtracting 438 from 510 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
73 can be fit into 720 9 times, resulting in a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 11007.01369
If we subtract 657 from 720, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
The number 73 fits into 630 8 times, leaving a remainder of 46.
The next digit of our result is 8. 
Result so far: 11007.013698
The remainder is 46 after subtracting 584 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
460 divided by 73 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 11007.0136986
The remainder is 22 after subtracting 438 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
When dividing 220 by 73, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 11007.01369863
Deduct 219 from 220 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 11007.01369863 with a remainder of 1e-09.
