We look at the division of 161775 by 81 
We want to divide 161775 by 81.

Let's proceed to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 81

Let's proceed to step 2:
16 divided by 81 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 81

Step 3:
When dividing 161 by 81, we get 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 81 away from 161, we end up with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 81

On to step 4:
The number 81 fits into 807 9 times, leaving a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 729 from 807 leaves us with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 81

On to step 5:
The number 81 fits into 787 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Deduct 729 from 787 and we're left with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 81

Going ahead to step 6:
The number 81 fits into 585 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 1997.0
If we subtract 567 from 585, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
81 goes into 180 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 1997.2
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 81, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1997.22
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 1997.22, and the remainder is 0.018.
