637019 ÷ 80 
Our goal is to divide 637019 by 80.

Going ahead to 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
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 80

Moving on to step 2:
When dividing 63 by 80, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 80

Let's proceed to step 3:
When dividing 637 by 80, we get 7 with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 560 from 637, we get 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 80

Step 4:
80 goes into 770 9 times with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 79.0
The remainder is 50 after subtracting 720 from 770.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 80

Moving on to step 5:
80 goes into 501 6 times with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Subtract 480 from 501 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 80

Step 6:
80 can be fit into 219 2 times, resulting in a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 7962.0
Subtracting 160 from 219 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
If we divide 590 by 80, we get 7 and a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 7962.7
Subtracting 560 from 590 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.

Step 8:
80 goes into 300 3 times with a remainder of 60.
The next digit of our result is 3. 
Result so far: 7962.73
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.

On to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7962.737
Subtract 560 from 600 to 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.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7962.7375
If we take 400 away from 400, 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.

Advancing 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: 7962.7375
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:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7962.7375
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.

The quotient of the division is 7962.7375, and the remainder is 0.0.
