Let's divide 158404 by 81
Our goal is to divide 158404 by 81.

Moving on to step 1:
When dividing 1 by 81, we get 0 with 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.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 81

Advancing to step 2:
81 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 81

Let's proceed to step 3:
The number 81 fits into 158 1 times, leaving a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 158 leaves us with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 81

Advancing to step 4:
The number 81 fits into 774 9 times, leaving a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 729 from 774 to get 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 81

Moving on to step 5:
If we divide 450 by 81, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we subtract 405 from 450, we get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 81

Let's proceed to step 6:
If we divide 454 by 81, we get 5 and a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 1955.0
Subtracting 405 from 454 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.

Step 7:
When dividing 490 by 81, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 1955.6
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 81, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1955.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 1955.604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 81 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 1955.6049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 1955.60493
If we take 243 away from 310, we end up 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.

Going ahead to step 12:
81 goes into 670 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1955.604938
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
If we divide 220 by 81, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 1955.6049382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
The number 81 fits into 580 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 1955.60493827
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.

After the division, we end up with 1955.60493827 and a remainder of 1.3e-08.
