When dividing 2560 by 396, we get 6 with a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 181657.6
If we take 2376 away from 2560, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 10:
1840 divided by 396 is 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 181657.64
Subtract 1584 from 1840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

When dividing 2560 by 396, we get 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 181657.646
If we subtract 2376 from 2560, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
The number 396 fits into 1840 4 times, leaving a remainder of 256.
The next digit of our result is 4. 
Result so far: 181657.6464
Subtract 1584 from 1840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
If we divide 2560 by 396, we get 6 and a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 181657.64646
If we take 2376 away from 2560, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 14:
The number 396 fits into 1840 4 times, leaving a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 181657.646464
Subtracting 1584 from 1840 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 15:
396 can be fit into 2560 6 times, resulting in a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 181657.6464646
The remainder is 184 after subtracting 2376 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
396 can be fit into 1840 4 times, resulting in a remainder of 256.
The next digit of our result is 4. 
Result so far: 181657.64646464
If we take 1584 away from 1840, we end up with 256.
