We look at the division of 666896 by 81 
Let's see how many times 81 fits into 666896.

Let's proceed 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
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 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
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 81

Advancing to step 3:
666 divided by 81 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 648 away from 666, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 81

Moving on to step 4:
81 can be fit into 188 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 26 after subtracting 162 from 188.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 81

Moving on to step 5:
269 divided by 81 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 823.0
Subtracting 243 from 269 leaves us with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 81

Let's proceed to step 6:
81 can be fit into 266 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 8233.0
Deduct 243 from 266 and we're left 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 7:
If we divide 230 by 81, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 8233.2
The remainder is 68 after subtracting 162 from 230.
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 8:
If we divide 680 by 81, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8233.28
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.

Going ahead to step 9:
If we divide 320 by 81, we get 3 and a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 8233.283
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.

Moving on to step 10:
When dividing 770 by 81, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 8233.2839
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.

Let's proceed to step 11:
When dividing 410 by 81, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8233.28395
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8233.28395
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.

On to step 13:
81 goes into 500 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 8233.2839506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
81 can be fit into 140 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 8233.28395061
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 8233.28395061 with a remaining 5.9e-08.
