We're dividing 73505311 by 321 
We're looking to find how many times 321 goes into 73505311.

Moving on to step 1:
The number 321 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 321

Going ahead to step 2:
321 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 321

Moving on to step 3:
The number 321 fits into 735 2 times, leaving a remainder of 93.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 642 from 735, we get 93.
Take the next digit (0) from the dividend and append it to 93, then repeat: 930 / 321

Step 4:
When dividing 930 by 321, we get 2 with a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 642 away from 930, we end up with 288.
Grab the next digit (5) from the dividend, add it to 288, then carry on: 2885 / 321

Going ahead to step 5:
The number 321 fits into 2885 8 times, leaving a remainder of 317.
Put 8 as the next digit of the answer. 
Result so far: 228.0
If we subtract 2568 from 2885, we get 317.
Bring next digit (3) of the dividend behind the 317 and repeat the process: 3173 / 321

Let's proceed to step 6:
If we divide 3173 by 321, we get 9 and a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 2289.0
If we subtract 2889 from 3173, we get 284.
Grab the next digit (1) from the dividend, add it to 284, then carry on: 2841 / 321

Advancing to step 7:
321 can be fit into 2841 8 times, resulting in a remainder of 273.
The number 8 becomes the next digit in our result. 
Result so far: 22898.0
If we take 2568 away from 2841, we end up with 273.
Include the next digit (1) from the dividend after 273, then repeat: 2731 / 321

Advancing to step 8:
321 goes into 2731 8 times with a remainder of 163.
Use 8 as the next digit of our solution. 
Result so far: 228988.0
If we subtract 2568 from 2731, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 9:
The number 321 fits into 1630 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 228988.5
Deduct 1605 from 1630 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 321, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 228988.5
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
When dividing 2500 by 321, we get 7 with a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 228988.507
Subtract 2247 from 2500 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 12:
When dividing 2530 by 321, we get 7 with a remainder of 283.
Put 7 as the next digit of the answer. 
Result so far: 228988.5077
If we take 2247 away from 2530, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Our division results in 228988.5077 with a remaining 0.00283.
