Let's divide 649516 by 81
Our goal is to divide 649516 by 81.

Going ahead to step 1:
81 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 81

Step 2:
The number 81 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 81

Moving on to step 3:
81 goes into 649 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 1 after subtracting 648 from 649.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 81

Going ahead to step 4:
81 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 15 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 81

Going ahead to step 5:
The number 81 fits into 151 1 times, leaving a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 801.0
If we take 81 away from 151, we end up with 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 81

Let's proceed to step 6:
81 can be fit into 706 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 8018.0
The remainder is 58 after subtracting 648 from 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
580 divided by 81 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8018.7
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 81 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 8018.71
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
490 divided by 81 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 8018.716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8018.716
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 81 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 8018.71604
If we take 324 away from 400, we end up with 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 12:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 8018.716049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
When dividing 310 by 81, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 8018.7160493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 14:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8018.71604938
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 8018.71604938 with a remainder of 2.2e-08.
