We look at the division of 147943 by 81 
We're looking to find how many times 81 goes into 147943.

Let's proceed to step 1:
The number 81 fits into 1 0 times, leaving 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 (4) from the dividend after 1, then repeat: 14 / 81

On to step 2:
14 divided by 81 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 81

On to step 3:
81 goes into 147 1 times with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 81 from 147, we get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 81

Let's proceed to step 4:
If we divide 669 by 81, we get 8 and a remainder of 21.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 648 from 669, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 81

Let's proceed to step 5:
If we divide 214 by 81, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
The remainder is 52 after subtracting 162 from 214.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 81

Moving on to step 6:
81 goes into 523 6 times with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 1826.0
Subtract 486 from 523 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 1826.4
Deduct 324 from 370 and we're left 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.

Advancing to step 8:
81 goes into 460 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 1826.45
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
81 goes into 550 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1826.456
If we subtract 486 from 550, we get 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 10:
If we divide 640 by 81, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 1826.4567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
If we divide 730 by 81, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1826.45679
Deduct 729 from 730 and we're left 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 12:
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: 1826.45679
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
81 goes into 100 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1826.4567901
If we take 81 away from 100, we end up 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.

On to step 14:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1826.45679012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1826.45679012 with a remainder of 2.8e-08.
