We divide 825664 by 81
We want to figure out the number of times 825664 can be divided by 81.

Step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 81

Let's proceed to step 2:
82 divided by 81 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 81 from 82.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 81

Going ahead to step 3:
The number 81 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 15, we get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 81

Advancing to step 4:
81 goes into 156 1 times with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 81 from 156 leaves us with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 81

Step 5:
81 goes into 756 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 1019.0
The remainder is 27 after subtracting 729 from 756.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 81

On to step 6:
When dividing 274 by 81, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 10193.0
If we subtract 243 from 274, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 10193.3
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 8:
When dividing 670 by 81, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 10193.38
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 9:
When dividing 220 by 81, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 10193.382
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.

Let's proceed to step 10:
When dividing 580 by 81, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 10193.3827
If we take 567 away from 580, we end up 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 11:
The number 81 fits into 130 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 10193.38271
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.

On to step 12:
490 divided by 81 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10193.382716
Deduct 486 from 490 and we're left with 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 13:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10193.382716
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 14:
400 divided by 81 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 10193.38271604
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 10193.38271604 with a remainder of 7.6e-08.
