3287563 ÷ 321 
We're looking to find how many times 321 goes into 3287563.

Step 1:
The number 321 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 321

Let's proceed to step 2:
When dividing 32 by 321, we get 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 321

Advancing to step 3:
When dividing 328 by 321, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 321 from 328 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 321

Step 4:
321 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 321

On to step 5:
When dividing 775 by 321, we get 2 with a remainder of 133.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 133 after subtracting 642 from 775.
Bring next digit (6) of the dividend behind the 133 and repeat the process: 1336 / 321

Advancing to step 6:
If we divide 1336 by 321, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1024.0
The remainder is 52 after subtracting 1284 from 1336.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 321

Let's proceed to step 7:
The number 321 fits into 523 1 times, leaving a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 10241.0
Subtract 321 from 523 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 8:
321 can be fit into 2020 6 times, resulting in a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 10241.6
Subtracting 1926 from 2020 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
If we divide 940 by 321, we get 2 and a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 10241.62
The remainder is 298 after subtracting 642 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 10:
321 can be fit into 2980 9 times, resulting in a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 10241.629
Deduct 2889 from 2980 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
910 divided by 321 is 2 with a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 10241.6292
Subtract 642 from 910 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 12:
If we divide 2680 by 321, we get 8 and a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 10241.62928
If we subtract 2568 from 2680, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
321 goes into 1120 3 times with a remainder of 157.
The next digit of our result is 3. 
Result so far: 10241.629283
Deduct 963 from 1120 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 14:
1570 divided by 321 is 4 with a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 10241.6292834
Deduct 1284 from 1570 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 15:
321 can be fit into 2860 8 times, resulting in a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 10241.62928348
If we subtract 2568 from 2860, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final outcome is 10241.62928348, with a leftover of 2.92e-07.
