Let's divide 66872902 by 81
Let's see how many times 81 fits into 66872902.

Advancing to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 81

Step 2:
When dividing 66 by 81, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 81

On to step 3:
If we divide 668 by 81, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 648 from 668 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 81

Let's proceed to step 4:
When dividing 207 by 81, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 162 from 207, we get 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 81

Going ahead to step 5:
If we divide 452 by 81, we get 5 and a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 825.0
Deduct 405 from 452 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 81

On to step 6:
When dividing 479 by 81, we get 5 with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 8255.0
Subtract 405 from 479 to get 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 81

Advancing to step 7:
81 goes into 740 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 82559.0
The remainder is 11 after subtracting 729 from 740.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 81

Let's proceed to step 8:
81 goes into 112 1 times with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 825591.0
The remainder is 31 after subtracting 81 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
If we divide 310 by 81, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 825591.3
Subtracting 243 from 310 leaves us 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.

Going ahead to step 10:
81 can be fit into 670 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 825591.38
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
If we divide 220 by 81, we get 2 and a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 825591.382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 825591.3827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
130 divided by 81 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 825591.38271
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.

Advancing to step 14:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 825591.382716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
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: 825591.382716
The remainder is 40 after subtracting 0 from 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 16:
81 goes into 400 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 825591.38271604
If we subtract 324 from 400, we 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.

In conclusion, the division gives 825591.38271604 with a balance of 7.6e-08.
