90256048 ÷ 393 
Let's see how many times 393 fits into 90256048.

Step 1:
9 divided by 393 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 393

Step 2:
393 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 393

Moving on to step 3:
If we divide 902 by 393, we get 2 and a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 786 from 902 to get 116.
Include the next digit (5) from the dividend after 116, then repeat: 1165 / 393

Going ahead to step 4:
When dividing 1165 by 393, we get 2 with a remainder of 379.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 786 from 1165, we get 379.
Include the next digit (6) from the dividend after 379, then repeat: 3796 / 393

Advancing to step 5:
3796 divided by 393 is 9 with a remainder of 259.
Use 9 as the next digit of our solution. 
Result so far: 229.0
The remainder is 259 after subtracting 3537 from 3796.
Bring next digit (0) of the dividend behind the 259 and repeat the process: 2590 / 393

Moving on to step 6:
When dividing 2590 by 393, we get 6 with a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 2296.0
If we take 2358 away from 2590, we end up with 232.
Include the next digit (4) from the dividend after 232, then repeat: 2324 / 393

Let's proceed to step 7:
2324 divided by 393 is 5 with a remainder of 359.
Record the quotient 5 as the next digit in the result. 
Result so far: 22965.0
Subtract 1965 from 2324 to get 359.
Include the next digit (8) from the dividend after 359, then repeat: 3598 / 393

On to step 8:
When dividing 3598 by 393, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 229659.0
Subtract 3537 from 3598 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
393 goes into 610 1 times with a remainder of 217.
Record the quotient 1 as the next digit in the result. 
Result so far: 229659.1
Subtracting 393 from 610 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 10:
2170 divided by 393 is 5 with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 229659.15
The remainder is 205 after subtracting 1965 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
When dividing 2050 by 393, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 229659.155
Subtract 1965 from 2050 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 229659.155 and a remainder of 0.0085.
