Let's divide 72664680 by 243
Our goal is to divide 72664680 by 243.

Going ahead to step 1:
If we divide 7 by 243, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 243

On to step 2:
The number 243 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 243

Let's proceed to step 3:
When dividing 726 by 243, we get 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 486 from 726 and we're left with 240.
Grab the next digit (6) from the dividend, add it to 240, then carry on: 2406 / 243

On to step 4:
If we divide 2406 by 243, we get 9 and a remainder of 219.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 2187 from 2406 and we're left with 219.
Include the next digit (4) from the dividend after 219, then repeat: 2194 / 243

Advancing to step 5:
When dividing 2194 by 243, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 299.0
Subtracting 2187 from 2194 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 243

Advancing to step 6:
243 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 2990.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 243

Moving on to step 7:
When dividing 768 by 243, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 29903.0
Deduct 729 from 768 and we're left with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 243

Advancing to step 8:
243 goes into 390 1 times with a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 299031.0
Deduct 243 from 390 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
When dividing 1470 by 243, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 299031.6
Deduct 1458 from 1470 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
If we divide 120 by 243, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 299031.6
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
1200 divided by 243 is 4 with a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 299031.604
Deduct 972 from 1200 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 12:
243 can be fit into 2280 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 299031.6049
If we subtract 2187 from 2280, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 13:
930 divided by 243 is 3 with a remainder of 201.
Write down 3 as next digit of the result. 
Result so far: 299031.60493
Subtract 729 from 930 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 14:
When dividing 2010 by 243, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 299031.604938
If we take 1944 away from 2010, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 15:
660 divided by 243 is 2 with a remainder of 174.
The next digit of our result is 2. 
Result so far: 299031.6049382
Subtract 486 from 660 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 16:
When dividing 1740 by 243, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 299031.60493827
Subtracting 1701 from 1740 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 299031.60493827, with a leftover of 3.9e-08.
