Let's divide 40518141 by 243
We're looking to find how many times 243 goes into 40518141.

Advancing to step 1:
The number 243 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 243

Moving on to step 2:
When dividing 40 by 243, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 243

Let's proceed to step 3:
When dividing 405 by 243, we get 1 with a remainder of 162.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 243 away from 405, we end up with 162.
Bring next digit (1) of the dividend behind the 162 and repeat the process: 1621 / 243

Advancing to step 4:
1621 divided by 243 is 6 with a remainder of 163.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 1458 away from 1621, we end up with 163.
Take the next digit (8) from the dividend and append it to 163, then repeat: 1638 / 243

Advancing to step 5:
243 goes into 1638 6 times with a remainder of 180.
The next digit of our result is 6. 
Result so far: 166.0
If we subtract 1458 from 1638, we get 180.
Append the next digit (1) from the dividend to 180 and continue with: 1801 / 243

Moving on to step 6:
243 can be fit into 1801 7 times, resulting in a remainder of 100.
The number 7 becomes the next digit in our result. 
Result so far: 1667.0
The remainder is 100 after subtracting 1701 from 1801.
Append the next digit (4) from the dividend to 100 and continue with: 1004 / 243

Moving on to step 7:
When dividing 1004 by 243, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 16674.0
The remainder is 32 after subtracting 972 from 1004.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 243

Let's proceed to step 8:
243 can be fit into 321 1 times, resulting in a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 166741.0
If we subtract 243 from 321, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
The number 243 fits into 780 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 166741.3
If we subtract 729 from 780, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
If we divide 510 by 243, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 166741.32
Subtracting 486 from 510 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
243 can be fit into 240 0 times, resulting in a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 166741.32
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
The number 243 fits into 2400 9 times, leaving a remainder of 213.
Use 9 as the next digit of our solution. 
Result so far: 166741.3209
If we take 2187 away from 2400, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 13:
The number 243 fits into 2130 8 times, leaving a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 166741.32098
Subtracting 1944 from 2130 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
The number 243 fits into 1860 7 times, leaving a remainder of 159.
Write down 7 as next digit of the result. 
Result so far: 166741.320987
The remainder is 159 after subtracting 1701 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 15:
The number 243 fits into 1590 6 times, leaving a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 166741.3209876
Deduct 1458 from 1590 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 16:
243 goes into 1320 5 times with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 166741.32098765
Deduct 1215 from 1320 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 166741.32098765 with a remaining 1.05e-07.
