73009955 divided by 321 
We want to divide 73009955 by 321.

Going ahead to step 1:
When dividing 7 by 321, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 321

Moving on to step 2:
The number 321 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 321

Let's proceed to step 3:
The number 321 fits into 730 2 times, leaving a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 642 away from 730, we end up with 88.
Fetch the next digit (0) from the dividend, attach it to 88 and continue: 880 / 321

Step 4:
When dividing 880 by 321, we get 2 with a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 642 from 880 and we're left with 238.
Append the next digit (9) from the dividend to 238 and continue with: 2389 / 321

Let's proceed to step 5:
321 can be fit into 2389 7 times, resulting in a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
The remainder is 142 after subtracting 2247 from 2389.
Take the next digit (9) from the dividend and append it to 142, then repeat: 1429 / 321

Let's proceed to step 6:
When dividing 1429 by 321, we get 4 with a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 2274.0
The remainder is 145 after subtracting 1284 from 1429.
Fetch the next digit (5) from the dividend, attach it to 145 and continue: 1455 / 321

Let's proceed to step 7:
The number 321 fits into 1455 4 times, leaving a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 22744.0
The remainder is 171 after subtracting 1284 from 1455.
Include the next digit (5) from the dividend after 171, then repeat: 1715 / 321

Let's proceed to step 8:
The number 321 fits into 1715 5 times, leaving a remainder of 110.
The next digit of our result is 5. 
Result so far: 227445.0
The remainder is 110 after subtracting 1605 from 1715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
321 goes into 1100 3 times with a remainder of 137.
The next digit of our result is 3. 
Result so far: 227445.3
If we subtract 963 from 1100, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
When dividing 1370 by 321, we get 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 227445.34
If we take 1284 away from 1370, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
When dividing 860 by 321, we get 2 with a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 227445.342
Deduct 642 from 860 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 12:
The number 321 fits into 2180 6 times, leaving a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 227445.3426
The remainder is 254 after subtracting 1926 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 13:
When dividing 2540 by 321, we get 7 with a remainder of 293.
The next digit of our result is 7. 
Result so far: 227445.34267
Deduct 2247 from 2540 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 14:
321 can be fit into 2930 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 227445.342679
If we take 2889 away from 2930, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
321 goes into 410 1 times with a remainder of 89.
The next digit of our result is 1. 
Result so far: 227445.3426791
If we take 321 away from 410, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 16:
When dividing 890 by 321, we get 2 with a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 227445.34267912
Subtract 642 from 890 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 227445.34267912 with a remainder of 2.48e-07.
