Let's divide 81222831 by 799
We want to divide 81222831 by 799.

Step 1:
799 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 799

Moving on to step 2:
If we divide 81 by 799, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 799

Step 3:
The number 799 fits into 812 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 799 from 812, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 799

Let's proceed to step 4:
799 can be fit into 132 0 times, resulting in a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 132 to get 132.
Fetch the next digit (2) from the dividend, attach it to 132 and continue: 1322 / 799

Step 5:
799 goes into 1322 1 times with a remainder of 523.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 799 away from 1322, we end up with 523.
Bring next digit (8) of the dividend behind the 523 and repeat the process: 5238 / 799

Moving on to step 6:
If we divide 5238 by 799, we get 6 and a remainder of 444.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
If we subtract 4794 from 5238, we get 444.
Append the next digit (3) from the dividend to 444 and continue with: 4443 / 799

On to step 7:
799 goes into 4443 5 times with a remainder of 448.
Use 5 as the next digit of our solution. 
Result so far: 10165.0
Subtracting 3995 from 4443 leaves us with 448.
Bring next digit (1) of the dividend behind the 448 and repeat the process: 4481 / 799

Let's proceed to step 8:
If we divide 4481 by 799, we get 5 and a remainder of 486.
Put 5 as the next digit of the answer. 
Result so far: 101655.0
If we subtract 3995 from 4481, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 9:
The number 799 fits into 4860 6 times, leaving a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 101655.6
Deduct 4794 from 4860 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
When dividing 660 by 799, we get 0 with a remainder of 660.
The next digit of our result is 0. 
Result so far: 101655.6
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 11:
The number 799 fits into 6600 8 times, leaving a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 101655.608
If we subtract 6392 from 6600, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 12:
799 goes into 2080 2 times with a remainder of 482.
Record the quotient 2 as the next digit in the result. 
Result so far: 101655.6082
The remainder is 482 after subtracting 1598 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 13:
The number 799 fits into 4820 6 times, leaving a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 101655.60826
Subtract 4794 from 4820 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
When dividing 260 by 799, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 101655.60826
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 15:
799 can be fit into 2600 3 times, resulting in a remainder of 203.
Use 3 as the next digit of our solution. 
Result so far: 101655.6082603
Subtract 2397 from 2600 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 16:
799 goes into 2030 2 times with a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 101655.60826032
Subtracting 1598 from 2030 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The quotient of the division is 101655.60826032, and the remainder is 4.32e-07.
