Let's divide 66642 by 80
We want to figure out the number of times 66642 can be divided by 80.

On to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 80

Going ahead to step 2:
80 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 80

Step 3:
80 can be fit into 666 8 times, resulting in a remainder of 26.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 640 from 666 leaves us with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 80

Let's proceed to step 4:
80 can be fit into 264 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we subtract 240 from 264, we get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 80

Let's proceed to step 5:
242 divided by 80 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 833.0
If we subtract 240 from 242, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
80 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 833.0
Subtract 0 from 20 to get 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 7:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 833.02
Deduct 160 from 200 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.

Moving on to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 833.025
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 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 833.025
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 10:
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: 833.025
Deduct 0 from 0 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.

In conclusion, the division gives 833.025 with a balance of 0.0.
