We look at the division of 90877896 by 243 
Let's see how many times 243 fits into 90877896.

Moving on to step 1:
243 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 243

Step 2:
243 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 243

On to step 3:
243 can be fit into 908 3 times, resulting in a remainder of 179.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 179 after subtracting 729 from 908.
Include the next digit (7) from the dividend after 179, then repeat: 1797 / 243

Going ahead to step 4:
If we divide 1797 by 243, we get 7 and a remainder of 96.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 1701 from 1797 to get 96.
Append the next digit (7) from the dividend to 96 and continue with: 967 / 243

Let's proceed to step 5:
If we divide 967 by 243, we get 3 and a remainder of 238.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
The remainder is 238 after subtracting 729 from 967.
Append the next digit (8) from the dividend to 238 and continue with: 2388 / 243

On to step 6:
243 can be fit into 2388 9 times, resulting in a remainder of 201.
The next digit of our result is 9. 
Result so far: 3739.0
Subtracting 2187 from 2388 leaves us with 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 243

On to step 7:
If we divide 2019 by 243, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 37398.0
If we subtract 1944 from 2019, we get 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 243

Going ahead to step 8:
When dividing 756 by 243, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 373983.0
If we subtract 729 from 756, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
243 can be fit into 270 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 373983.1
If we subtract 243 from 270, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
270 divided by 243 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 373983.11
If we subtract 243 from 270, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 373983.11, and the remainder is 0.027.
