We divide 66280 by 81
We want to figure out the number of times 66280 can be divided by 81.

Moving on to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 81

On to step 2:
If we divide 66 by 81, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 81

Advancing to step 3:
81 goes into 662 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 8.0
If we take 648 away from 662, we end up with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 81

Advancing to step 4:
148 divided by 81 is 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 81 from 148 leaves us with 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 81

Let's proceed to step 5:
670 divided by 81 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 818.0
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 818.2
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
580 divided by 81 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 818.27
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
The number 81 fits into 130 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 818.271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
81 goes into 490 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 818.2716
If we subtract 486 from 490, we 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.

Going ahead to step 10:
40 divided by 81 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 818.2716
Subtracting 0 from 40 leaves us 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.

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: 818.271604
Subtracting 324 from 400 leaves us 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.

Advancing to step 12:
When dividing 760 by 81, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 818.2716049
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
310 divided by 81 is 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 818.27160493
If we take 243 away from 310, we end up 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.

The final outcome is 818.27160493, with a leftover of 6.7e-08.
