178685 ÷ 81 
We want to divide 178685 by 81.

Moving on to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 81

Step 2:
If we divide 17 by 81, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 81

Going ahead to step 3:
81 can be fit into 178 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 162 from 178 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 81

Advancing to step 4:
When dividing 166 by 81, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 162 from 166 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 81

Step 5:
If we divide 48 by 81, we get 0 and a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 220.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 81

Step 6:
If we divide 485 by 81, we get 5 and a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 2205.0
If we subtract 405 from 485, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 2205.9
If we take 729 away from 800, we end up 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.

Going ahead to step 8:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 2205.98
If we take 648 away from 710, we end up 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.

Let's proceed to step 9:
If we divide 620 by 81, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 2205.987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2205.9876
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.

Advancing to step 11:
81 goes into 440 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2205.98765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
81 goes into 350 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2205.987654
Subtract 324 from 350 to get 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 13:
260 divided by 81 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2205.9876543
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.

Going ahead to step 14:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2205.98765432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 2205.98765432 with a remaining 8e-09.
