Let's divide 666341 by 80
We want to divide 666341 by 80.

Let's proceed to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

Advancing to step 2:
80 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 80

Advancing to step 3:
666 divided by 80 is 8 with 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.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 80

Let's proceed to step 4:
When dividing 263 by 80, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 240 from 263 leaves us with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 80

Let's proceed to step 5:
When dividing 234 by 80, we get 2 with a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 832.0
If we subtract 160 from 234, we get 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 80

Going ahead to step 6:
741 divided by 80 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 8329.0
The remainder is 21 after subtracting 720 from 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 80, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 8329.2
If we take 160 away from 210, 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.

On to step 8:
80 goes into 500 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8329.26
Subtract 480 from 500 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.

Going ahead to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 8329.262
If we subtract 160 from 200, we 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.

On to step 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8329.2625
Deduct 400 from 400 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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8329.2625
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8329.2625
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 quotient of the division is 8329.2625, and the remainder is 0.0.
