38790911 ÷ 243 
Our goal is to divide 38790911 by 243.

Step 1:
If we divide 3 by 243, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 243

On to step 2:
When dividing 38 by 243, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 243

Advancing to step 3:
The number 243 fits into 387 1 times, leaving a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 243 from 387 and we're left with 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 243

Step 4:
243 can be fit into 1449 5 times, resulting in a remainder of 234.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 1215 from 1449, we get 234.
Grab the next digit (0) from the dividend, add it to 234, then carry on: 2340 / 243

Advancing to step 5:
When dividing 2340 by 243, we get 9 with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 2187 from 2340 to get 153.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 243

Advancing to step 6:
If we divide 1539 by 243, we get 6 and a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 1596.0
If we take 1458 away from 1539, we end up with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 243

Going ahead to step 7:
243 goes into 811 3 times with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 15963.0
If we take 729 away from 811, we end up with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 243

Moving on to step 8:
821 divided by 243 is 3 with a remainder of 92.
Record the quotient 3 as the next digit in the result. 
Result so far: 159633.0
Subtract 729 from 821 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
When dividing 920 by 243, we get 3 with a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 159633.3
Deduct 729 from 920 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 10:
The number 243 fits into 1910 7 times, leaving a remainder of 209.
The next digit of our result is 7. 
Result so far: 159633.37
Subtract 1701 from 1910 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 11:
If we divide 2090 by 243, we get 8 and a remainder of 146.
The number 8 becomes the next digit in our result. 
Result so far: 159633.378
The remainder is 146 after subtracting 1944 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 12:
The number 243 fits into 1460 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 159633.3786
The remainder is 2 after subtracting 1458 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 243, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 159633.3786
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 243, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 159633.3786
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 159633.3786 and a remainder of 2e-05.
