We divide 90490287 by 321
Our goal is to divide 90490287 by 321.

Moving on to step 1:
When dividing 9 by 321, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 321

Let's proceed to step 2:
If we divide 90 by 321, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 321

Advancing to step 3:
If we divide 904 by 321, we get 2 and a remainder of 262.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 642 from 904 and we're left with 262.
Grab the next digit (9) from the dividend, add it to 262, then carry on: 2629 / 321

Step 4:
If we divide 2629 by 321, we get 8 and a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 2568 from 2629, we get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 321

Advancing to step 5:
When dividing 610 by 321, we get 1 with a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
The remainder is 289 after subtracting 321 from 610.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 321

Advancing to step 6:
2892 divided by 321 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2819.0
The remainder is 3 after subtracting 2889 from 2892.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 321

Step 7:
If we divide 38 by 321, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 28190.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 321

Let's proceed to step 8:
321 can be fit into 387 1 times, resulting in a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 281901.0
If we take 321 away from 387, we end up 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 9:
321 goes into 660 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 281901.2
Deduct 642 from 660 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 321 fits into 180 0 times, leaving a remainder of 180.
The next digit of our result is 0. 
Result so far: 281901.2
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
When dividing 1800 by 321, we get 5 with a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 281901.205
If we subtract 1605 from 1800, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 12:
321 goes into 1950 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 281901.2056
Subtracting 1926 from 1950 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.

Going ahead to step 13:
240 divided by 321 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 281901.2056
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
When dividing 2400 by 321, we get 7 with a remainder of 153.
Record the quotient 7 as the next digit in the result. 
Result so far: 281901.205607
If we subtract 2247 from 2400, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 15:
If we divide 1530 by 321, we get 4 and a remainder of 246.
Record the quotient 4 as the next digit in the result. 
Result so far: 281901.2056074
If we take 1284 away from 1530, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 16:
321 goes into 2460 7 times with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 281901.20560747
Subtracting 2247 from 2460 leaves us 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.

In conclusion, the division gives 281901.20560747 with a balance of 2.13e-07.
