80498779 ÷ 81 
We want to figure out the number of times 80498779 can be divided by 81.

Step 1:
8 divided by 81 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 81

Moving on to step 2:
81 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 81

Let's proceed to step 3:
81 can be fit into 804 9 times, resulting in a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 729 from 804, we get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 81

Let's proceed to step 4:
If we divide 759 by 81, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 729 from 759, we get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 81

Step 5:
When dividing 308 by 81, we get 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 993.0
Subtract 243 from 308 to get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 81

On to step 6:
The number 81 fits into 657 8 times, leaving a remainder of 9.
The next digit of our result is 8. 
Result so far: 9938.0
The remainder is 9 after subtracting 648 from 657.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 81

Advancing to step 7:
81 goes into 97 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 99381.0
If we take 81 away from 97, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 81

Going ahead to step 8:
When dividing 169 by 81, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 993812.0
If we take 162 away from 169, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 81 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 993812.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 81, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 993812.08
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
520 divided by 81 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 993812.086
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 993812.0864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 81, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 993812.08641
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
When dividing 790 by 81, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 993812.086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 15:
When dividing 610 by 81, we get 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 993812.0864197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 16:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 993812.08641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 993812.08641975 with a balance of 2.5e-08.
