Going ahead to step 3:
243 goes into 343 1 times with a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 243 away from 343, we end up with 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 243

Going ahead to step 4:
When dividing 1008 by 243, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 972 from 1008 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 243

Let's proceed to step 5:
The number 243 fits into 360 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtracting 243 from 360 leaves us with 117.
Fetch the next digit (9) from the dividend, attach it to 117 and continue: 1179 / 243

Going ahead to step 6:
243 goes into 1179 4 times with a remainder of 207.
Use 4 as the next digit of our solution. 
Result so far: 1414.0
The remainder is 207 after subtracting 972 from 1179.
Append the next digit (8) from the dividend to 207 and continue with: 2078 / 243

Moving on to step 7:
243 goes into 2078 8 times with a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 14148.0
The remainder is 134 after subtracting 1944 from 2078.
Fetch the next digit (3) from the dividend, attach it to 134 and continue: 1343 / 243

Moving on to step 8:
The number 243 fits into 1343 5 times, leaving a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 141485.0
Subtracting 1215 from 1343 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 9:
The number 243 fits into 1280 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 141485.5
Subtract 1215 from 1280 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
If we divide 650 by 243, we get 2 and a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 141485.52
The remainder is 164 after subtracting 486 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 11:
243 can be fit into 1640 6 times, resulting in a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 141485.526
Deduct 1458 from 1640 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 12:
If we divide 1820 by 243, we get 7 and a remainder of 119.
Use 7 as the next digit of our solution. 
Result so far: 141485.5267
Subtract 1701 from 1820 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 13:
243 can be fit into 1190 4 times, resulting in a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 141485.52674
Subtracting 972 from 1190 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 14:
When dividing 2180 by 243, we get 8 with a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 141485.526748
Subtracting 1944 from 2180 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 15:
If we divide 2360 by 243, we get 9 and a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 141485.5267489
If we take 2187 away from 2360, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 16:
When dividing 1730 by 243, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 141485.52674897
If we take 1701 away from 1730, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 141485.52674897 with a remainder of 2.9e-08.
