We look at the division of 584123 by 80 
We want to divide 584123 by 80.

Step 1:
5 divided by 80 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 80

Going ahead to step 2:
The number 80 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 80

Step 3:
The number 80 fits into 584 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 560 from 584 leaves us with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 80

Advancing to step 4:
241 divided by 80 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 240 from 241 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 80

On to step 5:
If we divide 12 by 80, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 730.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 80

Advancing to step 6:
80 goes into 123 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 7301.0
Deduct 80 from 123 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
430 divided by 80 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7301.5
Subtracting 400 from 430 leaves us 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.

Let's proceed to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 7301.53
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.

Advancing to step 9:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 7301.537
If we take 560 away from 600, we end up 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.
The number 5 becomes the next digit in our result. 
Result so far: 7301.5375
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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7301.5375
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.

On to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7301.5375
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 7301.5375, and the remainder is 0.0.
