We're dividing 660185 by 81 
Let's see how many times 81 fits into 660185.

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
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 81

Advancing to step 2:
81 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 81

Let's proceed to step 3:
660 divided by 81 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 12 after subtracting 648 from 660.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 81

Let's proceed to step 4:
81 can be fit into 121 1 times, resulting in a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 81 from 121 and we're left with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 81

Step 5:
When dividing 408 by 81, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 815.0
Deduct 405 from 408 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 81

Advancing to step 6:
81 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 8150.0
The remainder is 35 after subtracting 0 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
81 goes into 350 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 8150.4
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
If we divide 260 by 81, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 8150.43
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8150.432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 8150.432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
The number 81 fits into 800 9 times, leaving a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 8150.43209
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
When dividing 710 by 81, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 8150.432098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 8150.4320987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
If we divide 530 by 81, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 8150.43209876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 8150.43209876, and the remainder is 4.4e-08.
