616821 divided by 80 
We want to divide 616821 by 80.

Let's proceed to step 1:
80 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 80

Moving on to step 2:
61 divided by 80 is 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 80

Moving on to step 3:
If we divide 616 by 80, we get 7 and a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 560 from 616 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 80

Advancing to step 4:
80 can be fit into 568 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 560 from 568 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 80

On to step 5:
80 goes into 82 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 771.0
Subtract 80 from 82 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 80

Moving on to step 6:
When dividing 21 by 80, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 7710.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
210 divided by 80 is 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 7710.2
If we subtract 160 from 210, we get 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:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7710.26
If we subtract 480 from 500, we 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.

Step 9:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 7710.262
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7710.2625
Subtract 400 from 400 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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7710.2625
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:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7710.2625
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.

In conclusion, the division gives 7710.2625 with a balance of 0.0.
