We divide 839235 by 80
We're looking to find how many times 80 goes into 839235.

Let's proceed to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 80

Advancing to 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 take 80 away from 83, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

Moving on to step 3:
80 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 80

On to step 4:
392 divided by 80 is 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 104.0
The remainder is 72 after subtracting 320 from 392.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 80

Step 5:
When dividing 723 by 80, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1049.0
Subtracting 720 from 723 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 80

Let's proceed to step 6:
When dividing 35 by 80, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 10490.0
If we take 0 away from 35, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
When dividing 350 by 80, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 10490.4
The remainder is 30 after subtracting 320 from 350.
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:
80 goes into 300 3 times with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 10490.43
If we take 240 away from 300, we end up 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.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 10490.437
Subtracting 560 from 600 leaves us 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:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10490.4375
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.

Moving on to step 11:
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: 10490.4375
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10490.4375
If we subtract 0 from 0, we 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.

After the division, we end up with 10490.4375 and a remainder of 0.0.
