Let's divide 76518242 by 243
We're looking to find how many times 243 goes into 76518242.

Moving on to step 1:
If we divide 7 by 243, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 243

Let's proceed to step 2:
If we divide 76 by 243, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 243

Step 3:
When dividing 765 by 243, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 36 after subtracting 729 from 765.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 243

Advancing to step 4:
If we divide 361 by 243, we get 1 and a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 243 away from 361, we end up with 118.
Include the next digit (8) from the dividend after 118, then repeat: 1188 / 243

Let's proceed to step 5:
243 goes into 1188 4 times with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtract 972 from 1188 to get 216.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 243

Moving on to step 6:
The number 243 fits into 2162 8 times, leaving a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 3148.0
Subtract 1944 from 2162 to get 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 243

Advancing to step 7:
2184 divided by 243 is 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 31488.0
The remainder is 240 after subtracting 1944 from 2184.
Include the next digit (2) from the dividend after 240, then repeat: 2402 / 243

Moving on to step 8:
If we divide 2402 by 243, we get 9 and a remainder of 215.
The next digit of our result is 9. 
Result so far: 314889.0
The remainder is 215 after subtracting 2187 from 2402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 9:
The number 243 fits into 2150 8 times, leaving a remainder of 206.
The number 8 becomes the next digit in our result. 
Result so far: 314889.8
Subtract 1944 from 2150 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
When dividing 2060 by 243, we get 8 with a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 314889.88
The remainder is 116 after subtracting 1944 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 314889.88 with a remainder of 0.116.
