We look at the division of 661466 by 81 
Our goal is to divide 661466 by 81.

Moving on to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 81

Moving on to step 2:
If we divide 66 by 81, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 81

On to step 3:
81 goes into 661 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 648 from 661, we get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 81

Advancing to step 4:
81 can be fit into 134 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 81 from 134, we get 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 81

Let's proceed to step 5:
81 can be fit into 536 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 816.0
If we subtract 486 from 536, we get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 81

Going ahead to step 6:
When dividing 506 by 81, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8166.0
If we take 486 away from 506, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 81 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 8166.2
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
81 goes into 380 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 8166.24
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
The number 81 fits into 560 6 times, leaving a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 8166.246
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
When dividing 740 by 81, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 8166.2469
If we take 729 away from 740, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
81 goes into 110 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 8166.24691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
81 goes into 290 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 8166.246913
Subtract 243 from 290 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 8166.2469135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
81 can be fit into 650 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8166.24691358
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 8166.24691358 with a remaining 2e-09.
