We look at the division of 177813 by 81 
Let's see how many times 81 fits into 177813.

Let's proceed to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 81

Moving on to step 2:
81 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 81

On to step 3:
The number 81 fits into 177 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 162 away from 177, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 81

Moving on to step 4:
If we divide 158 by 81, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 81 away from 158, we end up with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 81

On to step 5:
When dividing 771 by 81, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 219.0
Deduct 729 from 771 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 81

Step 6:
423 divided by 81 is 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 2195.0
Deduct 405 from 423 and we're left 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.

Step 7:
The number 81 fits into 180 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 2195.2
Deduct 162 from 180 and we're left 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.

On to step 8:
When dividing 180 by 81, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2195.22
If we subtract 162 from 180, 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.

After the division, we end up with 2195.22 and a remainder of 0.018.
