We're dividing 25057333 by 321 
Let's see how many times 321 fits into 25057333.

Advancing to step 1:
2 divided by 321 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 321

Step 2:
When dividing 25 by 321, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 321

Let's proceed to step 3:
The number 321 fits into 250 0 times, leaving a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 250 to get 250.
Include the next digit (5) from the dividend after 250, then repeat: 2505 / 321

Step 4:
The number 321 fits into 2505 7 times, leaving a remainder of 258.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 258 after subtracting 2247 from 2505.
Include the next digit (7) from the dividend after 258, then repeat: 2587 / 321

Step 5:
2587 divided by 321 is 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 19 after subtracting 2568 from 2587.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 321

Step 6:
193 divided by 321 is 0 with a remainder of 193.
The next digit of our result is 0. 
Result so far: 780.0
The remainder is 193 after subtracting 0 from 193.
Include the next digit (3) from the dividend after 193, then repeat: 1933 / 321

On to step 7:
If we divide 1933 by 321, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 7806.0
The remainder is 7 after subtracting 1926 from 1933.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 321

Let's proceed to step 8:
When dividing 73 by 321, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 78060.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
When dividing 730 by 321, we get 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 78060.2
The remainder is 88 after subtracting 642 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
The number 321 fits into 880 2 times, leaving a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 78060.22
The remainder is 238 after subtracting 642 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 78060.22, with a leftover of 0.238.
