We're dividing 63063103 by 243 
Our goal is to divide 63063103 by 243.

Let's proceed to step 1:
When dividing 6 by 243, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 243

Step 2:
243 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 243

On to step 3:
243 goes into 630 2 times with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 486 from 630, we get 144.
Grab the next digit (6) from the dividend, add it to 144, then carry on: 1446 / 243

Going ahead to step 4:
243 goes into 1446 5 times with a remainder of 231.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 1215 from 1446, we get 231.
Fetch the next digit (3) from the dividend, attach it to 231 and continue: 2313 / 243

On to step 5:
When dividing 2313 by 243, we get 9 with a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Subtracting 2187 from 2313 leaves us with 126.
Fetch the next digit (1) from the dividend, attach it to 126 and continue: 1261 / 243

Going ahead to step 6:
When dividing 1261 by 243, we get 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 2595.0
If we take 1215 away from 1261, we end up with 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 243

Advancing to step 7:
The number 243 fits into 460 1 times, leaving a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 25951.0
If we take 243 away from 460, we end up with 217.
Include the next digit (3) from the dividend after 217, then repeat: 2173 / 243

Going ahead to step 8:
If we divide 2173 by 243, we get 8 and a remainder of 229.
Record the quotient 8 as the next digit in the result. 
Result so far: 259518.0
The remainder is 229 after subtracting 1944 from 2173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
If we divide 2290 by 243, we get 9 and a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 259518.9
The remainder is 103 after subtracting 2187 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
1030 divided by 243 is 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 259518.94
Deduct 972 from 1030 and we're left 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 11:
243 goes into 580 2 times with a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 259518.942
Subtract 486 from 580 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
When dividing 940 by 243, we get 3 with a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 259518.9423
The remainder is 211 after subtracting 729 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 13:
When dividing 2110 by 243, we get 8 with a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 259518.94238
If we subtract 1944 from 2110, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 14:
1660 divided by 243 is 6 with a remainder of 202.
Record the quotient 6 as the next digit in the result. 
Result so far: 259518.942386
Deduct 1458 from 1660 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 15:
2020 divided by 243 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 259518.9423868
The remainder is 76 after subtracting 1944 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
243 can be fit into 760 3 times, resulting in a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 259518.94238683
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 259518.94238683, with a leftover of 3.1e-08.
