603269 ÷ 80 
We want to figure out the number of times 603269 can be divided by 80.

On to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 80

Advancing to step 2:
80 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 80

On to step 3:
If we divide 603 by 80, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 560 from 603 to get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 80

Advancing to step 4:
80 goes into 432 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 400 away from 432, we end up with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 80

Advancing to step 5:
The number 80 fits into 326 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
If we take 320 away from 326, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 80

Step 6:
The number 80 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 7540.0
Deduct 0 from 69 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
When dividing 690 by 80, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 7540.8
If we take 640 away from 690, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 7540.86
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7540.862
Subtracting 160 from 200 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.

On to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7540.8625
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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7540.8625
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7540.8625
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.

The final result is 7540.8625 with a remainder of 0.0.
