168985 ÷ 81 
We want to figure out the number of times 168985 can be divided by 81.

Advancing to step 1:
1 divided by 81 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 81

On to step 2:
16 divided by 81 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 81

Step 3:
81 goes into 168 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
If we take 162 away from 168, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 81

Let's proceed to step 4:
The number 81 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 69 after subtracting 0 from 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 81

Step 5:
When dividing 698 by 81, we get 8 with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 208.0
The remainder is 50 after subtracting 648 from 698.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 81

Advancing to step 6:
The number 81 fits into 505 6 times, leaving a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 2086.0
Deduct 486 from 505 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2086.2
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
81 goes into 280 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 2086.23
Subtract 243 from 280 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
81 goes into 370 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 2086.234
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
81 can be fit into 460 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 2086.2345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 2086.23456
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
640 divided by 81 is 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 2086.234567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
If we divide 730 by 81, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2086.2345679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
81 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2086.2345679
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 2086.2345679 with a remainder of 1e-08.
