830819 divided by 80 
We're looking to find how many times 80 goes into 830819.

Let's proceed to step 1:
8 divided by 80 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 80

Advancing to step 2:
80 goes into 83 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 80 from 83 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 80

On to step 3:
If we divide 30 by 80, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 80

On to step 4:
80 goes into 308 3 times with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 103.0
The remainder is 68 after subtracting 240 from 308.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 80

Let's proceed to step 5:
80 can be fit into 681 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
Subtracting 640 from 681 leaves us with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 80

Advancing to step 6:
The number 80 fits into 419 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 10385.0
If we take 400 away from 419, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 80 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 10385.2
Subtract 160 from 190 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 10385.23
Subtracting 240 from 300 leaves us 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 9:
600 divided by 80 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10385.237
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10385.2375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10385.2375
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.

Moving on to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10385.2375
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 10385.2375 and a remainder of 0.0.
