Let's divide 90120818 by 323
We want to figure out the number of times 90120818 can be divided by 323.

Moving on to step 1:
If we divide 9 by 323, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 323

Going ahead to step 2:
323 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 323

Step 3:
The number 323 fits into 901 2 times, leaving a remainder of 255.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 646 from 901, we get 255.
Include the next digit (2) from the dividend after 255, then repeat: 2552 / 323

Moving on to step 4:
323 goes into 2552 7 times with a remainder of 291.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 291 after subtracting 2261 from 2552.
Append the next digit (0) from the dividend to 291 and continue with: 2910 / 323

On to step 5:
323 can be fit into 2910 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 279.0
If we subtract 2907 from 2910, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 323

Moving on to step 6:
323 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 2790.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 323

Going ahead to step 7:
If we divide 381 by 323, we get 1 and a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 27901.0
Subtract 323 from 381 to get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 323

Moving on to step 8:
If we divide 588 by 323, we get 1 and a remainder of 265.
The next digit of our result is 1. 
Result so far: 279011.0
The remainder is 265 after subtracting 323 from 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
When dividing 2650 by 323, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 279011.8
Deduct 2584 from 2650 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
When dividing 660 by 323, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 279011.82
Subtracting 646 from 660 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
140 divided by 323 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 279011.82
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
323 can be fit into 1400 4 times, resulting in a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 279011.8204
Subtract 1292 from 1400 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
When dividing 1080 by 323, we get 3 with a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 279011.82043
If we take 969 away from 1080, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 14:
The number 323 fits into 1110 3 times, leaving a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 279011.820433
Subtract 969 from 1110 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

The final outcome is 279011.820433, with a leftover of 1.41e-05.
