We're dividing 319502 by 80 
We want to figure out the number of times 319502 can be divided by 80.

Step 1:
3 divided by 80 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 80

Moving on to step 2:
The number 80 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 80

On to step 3:
When dividing 319 by 80, we get 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 79 after subtracting 240 from 319.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 80

Advancing to step 4:
80 goes into 795 9 times with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 720 from 795, we get 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 80

Advancing to step 5:
80 goes into 750 9 times with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 399.0
The remainder is 30 after subtracting 720 from 750.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 80

Let's proceed to step 6:
The number 80 fits into 302 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 3993.0
Subtract 240 from 302 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
80 can be fit into 620 7 times, resulting in a remainder of 60.
The next digit of our result is 7. 
Result so far: 3993.7
Deduct 560 from 620 and we're left 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.

Moving on to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3993.77
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 3993.77, and the remainder is 0.04.
