We're dividing 73216542 by 321 
Our goal is to divide 73216542 by 321.

Let's proceed to step 1:
321 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 321

Step 2:
The number 321 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 321

On to step 3:
321 goes into 732 2 times with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 90 after subtracting 642 from 732.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 321

Let's proceed to step 4:
901 divided by 321 is 2 with a remainder of 259.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 642 from 901 leaves us with 259.
Bring next digit (6) of the dividend behind the 259 and repeat the process: 2596 / 321

Step 5:
2596 divided by 321 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
If we subtract 2568 from 2596, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 321

Let's proceed to step 6:
321 can be fit into 285 0 times, resulting in a remainder of 285.
The next digit of our result is 0. 
Result so far: 2280.0
The remainder is 285 after subtracting 0 from 285.
Fetch the next digit (4) from the dividend, attach it to 285 and continue: 2854 / 321

Let's proceed to step 7:
321 can be fit into 2854 8 times, resulting in a remainder of 286.
Put 8 as the next digit of the answer. 
Result so far: 22808.0
If we subtract 2568 from 2854, we get 286.
Fetch the next digit (2) from the dividend, attach it to 286 and continue: 2862 / 321

Moving on to step 8:
When dividing 2862 by 321, we get 8 with a remainder of 294.
Put 8 as the next digit of the answer. 
Result so far: 228088.0
If we subtract 2568 from 2862, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
If we divide 2940 by 321, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 228088.9
Subtract 2889 from 2940 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
321 goes into 510 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 228088.91
Subtracting 321 from 510 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 11:
1890 divided by 321 is 5 with a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 228088.915
If we subtract 1605 from 1890, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 12:
If we divide 2850 by 321, we get 8 and a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 228088.9158
If we subtract 2568 from 2850, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 13:
When dividing 2820 by 321, we get 8 with a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 228088.91588
If we take 2568 away from 2820, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 228088.91588, with a leftover of 0.000252.
