We look at the division of 158316 by 81 
Let's see how many times 81 fits into 158316.

Let's proceed to step 1:
1 divided by 81 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 81

Advancing to step 2:
If we divide 15 by 81, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 81

Advancing to step 3:
If we divide 158 by 81, we get 1 and a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 81 from 158, we get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 81

Going ahead to step 4:
The number 81 fits into 773 9 times, leaving a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 729 from 773 leaves us with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 81

Let's proceed to step 5:
If we divide 441 by 81, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 195.0
If we take 405 away from 441, we end up with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 81

Advancing to step 6:
The number 81 fits into 366 4 times, leaving a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1954.0
The remainder is 42 after subtracting 324 from 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
81 can be fit into 420 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1954.5
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 1954.51
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
If we divide 690 by 81, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 1954.518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1954.5185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 1954.51851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
If we divide 690 by 81, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1954.518518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
When dividing 420 by 81, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1954.5185185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
When dividing 150 by 81, we get 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 1954.51851851
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 1954.51851851 with a remainder of 6.9e-08.
