10080499 divided by 321 
We want to figure out the number of times 10080499 can be divided by 321.

Advancing to step 1:
When dividing 1 by 321, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 321

Advancing to step 2:
321 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 321

Let's proceed to step 3:
The number 321 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 100 after subtracting 0 from 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 321

On to step 4:
When dividing 1008 by 321, we get 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 963 from 1008 and we're left with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 321

Advancing to step 5:
When dividing 450 by 321, we get 1 with a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 321 from 450 leaves us with 129.
Grab the next digit (4) from the dividend, add it to 129, then carry on: 1294 / 321

Step 6:
If we divide 1294 by 321, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 314.0
Subtracting 1284 from 1294 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 321

On to step 7:
If we divide 109 by 321, we get 0 and a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 3140.0
If we take 0 away from 109, we end up with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 321

Moving on to step 8:
If we divide 1099 by 321, we get 3 and a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 31403.0
Deduct 963 from 1099 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 9:
If we divide 1360 by 321, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 31403.4
If we take 1284 away from 1360, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 321, we get 2 and a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 31403.42
Subtracting 642 from 760 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 11:
When dividing 1180 by 321, we get 3 with a remainder of 217.
Record the quotient 3 as the next digit in the result. 
Result so far: 31403.423
Deduct 963 from 1180 and we're left 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 12:
If we divide 2170 by 321, we get 6 and a remainder of 244.
The next digit of our result is 6. 
Result so far: 31403.4236
The remainder is 244 after subtracting 1926 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 13:
When dividing 2440 by 321, we get 7 with a remainder of 193.
The next digit of our result is 7. 
Result so far: 31403.42367
If we subtract 2247 from 2440, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 14:
The number 321 fits into 1930 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 31403.423676
If we subtract 1926 from 1930, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
40 divided by 321 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 31403.423676
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
If we divide 400 by 321, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 31403.42367601
Subtract 321 from 400 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 31403.42367601 with a balance of 7.9e-08.
