We look at the division of 803960 by 75 
We want to figure out the number of times 803960 can be divided by 75.

Moving 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
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 75

Going ahead to step 2:
80 divided by 75 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 75 away from 80, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 75

Let's proceed to step 3:
53 divided by 75 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 53, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 75

Let's proceed to step 4:
When dividing 539 by 75, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtract 525 from 539 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 75

Advancing to step 5:
146 divided by 75 is 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
Subtract 75 from 146 to get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 75

Let's proceed to step 6:
If we divide 710 by 75, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 10719.0
If we subtract 675 from 710, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 75 fits into 350 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 10719.4
The remainder is 50 after subtracting 300 from 350.
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 8:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 10719.46
The remainder is 50 after subtracting 450 from 500.
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.
Record the quotient 6 as the next digit in the result. 
Result so far: 10719.466
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 final outcome is 10719.466, with a leftover of 0.005.
