We look at the division of 831948 by 80 
Let's see how many times 80 fits into 831948.

Moving on to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 80

Step 2:
If we divide 83 by 80, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 83, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 80

Let's proceed to step 3:
When dividing 31 by 80, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 80

Let's proceed to step 4:
80 can be fit into 319 3 times, resulting in a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 240 away from 319, we end up with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 80

Going ahead to step 5:
80 can be fit into 794 9 times, resulting in a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
Subtract 720 from 794 to get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 80

Step 6:
If we divide 748 by 80, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 10399.0
If we subtract 720 from 748, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
The number 80 fits into 280 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 10399.3
If we subtract 240 from 280, 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.

On to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10399.35
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.

Let's proceed to step 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10399.35
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10399.35
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.

The final result is 10399.35 with a remainder of 0.0.
