We're dividing 420794 by 80 
We want to divide 420794 by 80.

Let's proceed to step 1:
4 divided by 80 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 80

Step 2:
When dividing 42 by 80, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 80

Going ahead to step 3:
80 can be fit into 420 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 400 from 420 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 80

Moving on to step 4:
207 divided by 80 is 2 with a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 160 from 207 leaves us with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 80

Let's proceed to step 5:
80 goes into 479 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 525.0
Deduct 400 from 479 and we're left with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 80

Step 6:
80 goes into 794 9 times with a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 5259.0
Deduct 720 from 794 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
If we divide 740 by 80, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 5259.9
Subtract 720 from 740 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 5259.92
If we subtract 160 from 200, 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.

Going ahead to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5259.925
Subtracting 400 from 400 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.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5259.925
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.

Going ahead to step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5259.925
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 5259.925 and a remainder of 0.0.
