142507 ÷ 80 
We want to figure out the number of times 142507 can be divided by 80.

On to step 1:
80 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 80

Step 2:
If we divide 14 by 80, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 80

Advancing to step 3:
If we divide 142 by 80, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 142 leaves us with 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 80

Let's proceed to step 4:
80 goes into 625 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 560 away from 625, we end up with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 80

Going ahead to step 5:
650 divided by 80 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we take 640 away from 650, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 80

On to step 6:
When dividing 107 by 80, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1781.0
Subtract 80 from 107 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
80 can be fit into 270 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1781.3
If we take 240 away from 270, we end up 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.

Advancing to step 8:
80 goes into 300 3 times with a remainder of 60.
The next digit of our result is 3. 
Result so far: 1781.33
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.

The quotient of the division is 1781.33, and the remainder is 0.06.
