65006821 divided by 80 
We want to figure out the number of times 65006821 can be divided by 80.

Going ahead to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 80

Moving on to step 2:
80 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 80

Moving on to step 3:
When dividing 650 by 80, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 640 from 650, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 80

On to step 4:
When dividing 100 by 80, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 80 from 100 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 80

Moving on to step 5:
80 goes into 206 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 812.0
The remainder is 46 after subtracting 160 from 206.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 80

Moving on to step 6:
80 can be fit into 468 5 times, resulting in a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 8125.0
Subtract 400 from 468 to get 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 80

Advancing to step 7:
80 can be fit into 682 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 81258.0
If we subtract 640 from 682, we get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 80

On to step 8:
80 goes into 421 5 times with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 812585.0
Subtracting 400 from 421 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
80 goes into 210 2 times with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 812585.2
Subtracting 160 from 210 leaves us 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.

Going ahead to step 10:
500 divided by 80 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 812585.26
Deduct 480 from 500 and we're left 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 11:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 812585.262
Subtract 160 from 200 to 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.

Going ahead to step 12:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 812585.2625
If we subtract 400 from 400, 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.

Let's proceed to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 812585.2625
Subtracting 0 from 0 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.

Advancing to step 14:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 812585.2625
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.

The final result is 812585.2625 with a remainder of 0.0.
