We're dividing 664250 by 81 
We want to divide 664250 by 81.

Let's proceed to step 1:
81 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 81

On to step 2:
81 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 81

On to step 3:
The number 81 fits into 664 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 648 from 664, we get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 81

Step 4:
81 goes into 162 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 162 from 162 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 81

Step 5:
81 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 81

Step 6:
81 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8200.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
81 goes into 500 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 8200.6
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 81 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 8200.61
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 81, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8200.617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
81 goes into 230 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 8200.6172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
81 goes into 680 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8200.61728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 81 is 3 with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 8200.617283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 13:
770 divided by 81 is 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 8200.6172839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
If we divide 410 by 81, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8200.61728395
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 8200.61728395 with a remainder of 5e-09.
