We look at the division of 331035 by 80 
Our goal is to divide 331035 by 80.

On to step 1:
The number 80 fits into 3 0 times, leaving 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.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 80

Going ahead to step 2:
80 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 80

Moving on to step 3:
When dividing 331 by 80, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 320 from 331 to get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 80

Advancing to step 4:
If we divide 110 by 80, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 80 away from 110, we end up with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 80

On to step 5:
When dividing 303 by 80, we get 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 413.0
If we subtract 240 from 303, we get 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 80

Moving on to step 6:
If we divide 635 by 80, we get 7 and a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 4137.0
If we take 560 away from 635, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
When dividing 750 by 80, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 4137.9
If we take 720 away from 750, we end up with 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:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 4137.93
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 4137.937
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4137.9375
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4137.9375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4137.9375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4137.9375, and the remainder is 0.0.
