80799007 divided by 821 
Our goal is to divide 80799007 by 821.

Moving on to step 1:
When dividing 8 by 821, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 821

Step 2:
The number 821 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 821

Moving on to step 3:
If we divide 807 by 821, we get 0 and a remainder of 807.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 807 to get 807.
Grab the next digit (9) from the dividend, add it to 807, then carry on: 8079 / 821

Step 4:
8079 divided by 821 is 9 with a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7389 away from 8079, we end up with 690.
Append the next digit (9) from the dividend to 690 and continue with: 6909 / 821

Moving on to step 5:
821 goes into 6909 8 times with a remainder of 341.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 6568 from 6909 and we're left with 341.
Bring next digit (0) of the dividend behind the 341 and repeat the process: 3410 / 821

Advancing to step 6:
If we divide 3410 by 821, we get 4 and a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 984.0
If we subtract 3284 from 3410, we get 126.
Append the next digit (0) from the dividend to 126 and continue with: 1260 / 821

Moving on to step 7:
821 can be fit into 1260 1 times, resulting in a remainder of 439.
The next digit of our result is 1. 
Result so far: 9841.0
Deduct 821 from 1260 and we're left with 439.
Grab the next digit (7) from the dividend, add it to 439, then carry on: 4397 / 821

Step 8:
4397 divided by 821 is 5 with a remainder of 292.
The next digit of our result is 5. 
Result so far: 98415.0
If we take 4105 away from 4397, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 9:
If we divide 2920 by 821, we get 3 and a remainder of 457.
The number 3 becomes the next digit in our result. 
Result so far: 98415.3
If we subtract 2463 from 2920, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 10:
821 can be fit into 4570 5 times, resulting in a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 98415.35
Subtract 4105 from 4570 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 11:
821 goes into 4650 5 times with a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 98415.355
The remainder is 545 after subtracting 4105 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The quotient of the division is 98415.355, and the remainder is 0.0545.
