43420716 divided by 243 
Let's see how many times 243 fits into 43420716.

On to step 1:
4 divided by 243 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 243

Step 2:
243 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 243

Going ahead to step 3:
243 can be fit into 434 1 times, resulting in a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 243 from 434 leaves us with 191.
Include the next digit (2) from the dividend after 191, then repeat: 1912 / 243

Let's proceed to step 4:
243 can be fit into 1912 7 times, resulting in a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 1701 from 1912 leaves us with 211.
Append the next digit (0) from the dividend to 211 and continue with: 2110 / 243

Step 5:
243 can be fit into 2110 8 times, resulting in a remainder of 166.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we take 1944 away from 2110, we end up with 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 243

On to step 6:
243 can be fit into 1667 6 times, resulting in a remainder of 209.
Write down 6 as next digit of the result. 
Result so far: 1786.0
The remainder is 209 after subtracting 1458 from 1667.
Fetch the next digit (1) from the dividend, attach it to 209 and continue: 2091 / 243

Step 7:
When dividing 2091 by 243, we get 8 with a remainder of 147.
The number 8 becomes the next digit in our result. 
Result so far: 17868.0
Subtract 1944 from 2091 to get 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 243

Step 8:
1476 divided by 243 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 178686.0
Deduct 1458 from 1476 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
If we divide 180 by 243, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 178686.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
When dividing 1800 by 243, we get 7 with a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 178686.07
If we subtract 1701 from 1800, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 11:
The number 243 fits into 990 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 178686.074
Deduct 972 from 990 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
243 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 178686.074
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
243 goes into 1800 7 times with a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 178686.07407
If we subtract 1701 from 1800, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 14:
The number 243 fits into 990 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 178686.074074
The remainder is 18 after subtracting 972 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
When dividing 180 by 243, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 178686.074074
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
The number 243 fits into 1800 7 times, leaving a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 178686.07407407
If we take 1701 away from 1800, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final result is 178686.07407407 with a remainder of 9.9e-08.
