We look at the division of 71599794 by 321 
We're looking to find how many times 321 goes into 71599794.

Moving on to step 1:
321 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 321

Moving on to step 2:
321 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 321

Step 3:
321 can be fit into 715 2 times, resulting in a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 642 from 715 leaves us with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 321

On to step 4:
321 can be fit into 739 2 times, resulting in a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 642 from 739 to get 97.
Take the next digit (9) from the dividend and append it to 97, then repeat: 979 / 321

Advancing to step 5:
If we divide 979 by 321, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 223.0
If we take 963 away from 979, we end up with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 321

Step 6:
321 goes into 167 0 times with a remainder of 167.
Record the quotient 0 as the next digit in the result. 
Result so far: 2230.0
Subtracting 0 from 167 leaves us with 167.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 321

Advancing to step 7:
321 goes into 1679 5 times with a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 22305.0
Subtracting 1605 from 1679 leaves us with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 321

Let's proceed to step 8:
321 goes into 744 2 times with a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 223052.0
Deduct 642 from 744 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
1020 divided by 321 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 223052.3
If we take 963 away from 1020, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
321 goes into 570 1 times with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 223052.31
Subtracting 321 from 570 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 11:
321 goes into 2490 7 times with a remainder of 243.
The number 7 becomes the next digit in our result. 
Result so far: 223052.317
Subtracting 2247 from 2490 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 12:
When dividing 2430 by 321, we get 7 with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 223052.3177
Deduct 2247 from 2430 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

After the division, we end up with 223052.3177 and a remainder of 0.00183.
