42772889 ÷ 243 
We're looking to find how many times 243 goes into 42772889.

Step 1:
243 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 243

On to step 2:
The number 243 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 243

Moving on to step 3:
243 goes into 427 1 times with a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 184 after subtracting 243 from 427.
Grab the next digit (7) from the dividend, add it to 184, then carry on: 1847 / 243

Moving on to step 4:
243 goes into 1847 7 times with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 1701 from 1847, we get 146.
Bring next digit (2) of the dividend behind the 146 and repeat the process: 1462 / 243

On to step 5:
243 goes into 1462 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we take 1458 away from 1462, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 243

On to step 6:
48 divided by 243 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 1760.0
Subtract 0 from 48 to get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 243

Moving on to step 7:
243 goes into 488 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 17602.0
The remainder is 2 after subtracting 486 from 488.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 243

Step 8:
When dividing 29 by 243, we get 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 176020.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
243 goes into 290 1 times with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 176020.1
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
243 goes into 470 1 times with a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 176020.11
If we subtract 243 from 470, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final result is 176020.11 with a remainder of 0.227.
