158320 divided by 81 
Our goal is to divide 158320 by 81.

Let's proceed to step 1:
1 divided by 81 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 81

On to step 2:
81 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 81

On to step 3:
81 goes into 158 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 158 leaves us with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 81

Advancing to step 4:
When dividing 773 by 81, we get 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 729 from 773 leaves us with 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 81

Step 5:
If we divide 442 by 81, we get 5 and a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 195.0
The remainder is 37 after subtracting 405 from 442.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 81

Let's proceed to step 6:
81 can be fit into 370 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 1954.0
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
If we divide 460 by 81, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 1954.5
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
550 divided by 81 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1954.56
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
640 divided by 81 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 1954.567
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
When dividing 730 by 81, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1954.5679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1954.5679
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 81, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1954.567901
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
81 goes into 190 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1954.5679012
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
The number 81 fits into 280 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1954.56790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 1954.56790123 with a remaining 3.7e-08.
