We're dividing 71578896 by 321 
We want to divide 71578896 by 321.

Let's proceed to step 1:
The number 321 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 321

Going ahead to step 2:
The number 321 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 321

On to step 3:
321 goes into 715 2 times with a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 642 from 715 and we're left with 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 321

Going ahead to step 4:
When dividing 737 by 321, we get 2 with a remainder of 95.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 642 from 737 leaves us with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 321

Moving on to step 5:
The number 321 fits into 958 2 times, leaving a remainder of 316.
Write down 2 as next digit of the result. 
Result so far: 222.0
Deduct 642 from 958 and we're left with 316.
Append the next digit (8) from the dividend to 316 and continue with: 3168 / 321

Moving on to step 6:
321 can be fit into 3168 9 times, resulting in a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 2229.0
The remainder is 279 after subtracting 2889 from 3168.
Fetch the next digit (9) from the dividend, attach it to 279 and continue: 2799 / 321

Step 7:
The number 321 fits into 2799 8 times, leaving a remainder of 231.
Record the quotient 8 as the next digit in the result. 
Result so far: 22298.0
Subtracting 2568 from 2799 leaves us with 231.
Append the next digit (6) from the dividend to 231 and continue with: 2316 / 321

Going ahead to step 8:
321 can be fit into 2316 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 222987.0
Subtracting 2247 from 2316 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
The number 321 fits into 690 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 222987.2
Deduct 642 from 690 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
The number 321 fits into 480 1 times, leaving a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 222987.21
If we take 321 away from 480, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 11:
321 can be fit into 1590 4 times, resulting in a remainder of 306.
The next digit of our result is 4. 
Result so far: 222987.214
The remainder is 306 after subtracting 1284 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 12:
321 goes into 3060 9 times with a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 222987.2149
Subtracting 2889 from 3060 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 13:
The number 321 fits into 1710 5 times, leaving a remainder of 105.
The next digit of our result is 5. 
Result so far: 222987.21495
The remainder is 105 after subtracting 1605 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 14:
321 can be fit into 1050 3 times, resulting in a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 222987.214953
Subtracting 963 from 1050 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 15:
If we divide 870 by 321, we get 2 and a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 222987.2149532
If we take 642 away from 870, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 16:
321 can be fit into 2280 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 222987.21495327
Subtracting 2247 from 2280 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 222987.21495327, with a leftover of 3.3e-08.
