We're dividing 161878 by 81 
Our goal is to divide 161878 by 81.

Moving on to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 81

Step 2:
When dividing 16 by 81, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 81

On to step 3:
The number 81 fits into 161 1 times, leaving a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 161, we end up with 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 81

Step 4:
81 goes into 808 9 times with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 79 after subtracting 729 from 808.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 81

Step 5:
The number 81 fits into 797 9 times, leaving a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 199.0
If we subtract 729 from 797, we get 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 81

Let's proceed to step 6:
81 can be fit into 688 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 1998.0
Subtracting 648 from 688 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
When dividing 400 by 81, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 1998.4
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 1998.49
If we subtract 729 from 760, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 1998.493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1998.4938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 81, we get 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 1998.49382
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1998.493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 81 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1998.4938271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
490 divided by 81 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1998.49382716
If we take 486 away from 490, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1998.49382716 with a remaining 4e-09.
