We divide 660953 by 81
We want to figure out the number of times 660953 can be divided by 81.

Moving on to step 1:
6 divided by 81 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 81

Going ahead to 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
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 81

On to step 3:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 648 from 660 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 81

Advancing to step 4:
If we divide 129 by 81, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 81 from 129, we get 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 81

Step 5:
485 divided by 81 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 815.0
If we take 405 away from 485, we end up with 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 81

Let's proceed to step 6:
81 can be fit into 803 9 times, resulting in a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 8159.0
If we subtract 729 from 803, we 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.

On to step 7:
81 can be fit into 740 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 8159.9
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 8159.91
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
When dividing 290 by 81, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 8159.913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
The number 81 fits into 470 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 8159.9135
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
The number 81 fits into 650 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8159.91358
Subtracting 648 from 650 leaves us 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.

Step 12:
If we divide 20 by 81, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8159.91358
Subtracting 0 from 20 leaves us 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.

Step 13:
The number 81 fits into 200 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 8159.9135802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
81 goes into 380 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 8159.91358024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 8159.91358024 with a remaining 5.6e-08.
