80579844 divided by 821 
We want to figure out the number of times 80579844 can be divided by 821.

Advancing to step 1:
821 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 821

Step 2:
80 divided by 821 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 821

Going ahead to step 3:
805 divided by 821 is 0 with a remainder of 805.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 805 after subtracting 0 from 805.
Include the next digit (7) from the dividend after 805, then repeat: 8057 / 821

Moving on to step 4:
821 goes into 8057 9 times with a remainder of 668.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7389 from 8057 and we're left with 668.
Append the next digit (9) from the dividend to 668 and continue with: 6689 / 821

Let's proceed to step 5:
6689 divided by 821 is 8 with a remainder of 121.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtract 6568 from 6689 to get 121.
Include the next digit (8) from the dividend after 121, then repeat: 1218 / 821

Advancing to step 6:
The number 821 fits into 1218 1 times, leaving a remainder of 397.
Write down 1 as next digit of the result. 
Result so far: 981.0
If we subtract 821 from 1218, we get 397.
Take the next digit (4) from the dividend and append it to 397, then repeat: 3974 / 821

On to step 7:
If we divide 3974 by 821, we get 4 and a remainder of 690.
The number 4 becomes the next digit in our result. 
Result so far: 9814.0
Subtracting 3284 from 3974 leaves us with 690.
Grab the next digit (4) from the dividend, add it to 690, then carry on: 6904 / 821

Step 8:
6904 divided by 821 is 8 with a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 98148.0
Subtracting 6568 from 6904 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 9:
821 can be fit into 3360 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 98148.4
Subtract 3284 from 3360 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
If we divide 760 by 821, we get 0 and a remainder of 760.
Use 0 as the next digit of our solution. 
Result so far: 98148.4
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 11:
When dividing 7600 by 821, we get 9 with a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 98148.409
Deduct 7389 from 7600 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 12:
When dividing 2110 by 821, we get 2 with a remainder of 468.
Put 2 as the next digit of the answer. 
Result so far: 98148.4092
Subtract 1642 from 2110 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 13:
4680 divided by 821 is 5 with a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 98148.40925
If we take 4105 away from 4680, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 14:
The number 821 fits into 5750 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 98148.409257
If we subtract 5747 from 5750, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 15:
If we divide 30 by 821, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 98148.409257
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
821 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 98148.409257
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 98148.409257, and the remainder is 3e-07.
