We divide 803573 by 75
We want to divide 803573 by 75.

On to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 75

On to step 2:
If we divide 80 by 75, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 75 from 80, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 75

Step 3:
If we divide 53 by 75, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 53 to get 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 75

Moving on to step 4:
The number 75 fits into 535 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 10 after subtracting 525 from 535.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 75

On to step 5:
107 divided by 75 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
If we take 75 away from 107, we end up with 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 75

On to step 6:
If we divide 323 by 75, we get 4 and a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 10714.0
If we take 300 away from 323, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 75 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 10714.3
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 75, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 10714.3
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 10714.306
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 75 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 10714.3066
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 10714.3066, and the remainder is 0.0005.
