We divide 602423 by 80
We're looking to find how many times 80 goes into 602423.

Step 1:
80 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 80

Step 2:
60 divided by 80 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 80

Step 3:
80 can be fit into 602 7 times, resulting in a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 560 from 602, we get 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 80

On to step 4:
The number 80 fits into 424 5 times, leaving a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 400 from 424 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 80

Going ahead to step 5:
The number 80 fits into 242 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 753.0
Deduct 240 from 242 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 80

Step 6:
The number 80 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 7530.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
80 can be fit into 230 2 times, resulting in a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 7530.2
Subtract 160 from 230 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 7530.28
The remainder is 60 after subtracting 640 from 700.
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:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7530.287
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.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7530.2875
If we subtract 400 from 400, 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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7530.2875
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7530.2875
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.

The quotient of the division is 7530.2875, and the remainder is 0.0.
