57211090 ÷ 396 
We're looking to find how many times 396 goes into 57211090.

Step 1:
The number 396 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 396

Advancing to step 2:
396 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 396

Let's proceed to step 3:
396 can be fit into 572 1 times, resulting in a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 396 from 572 and we're left with 176.
Append the next digit (1) from the dividend to 176 and continue with: 1761 / 396

Moving on to step 4:
396 goes into 1761 4 times with a remainder of 177.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1584 from 1761, we get 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 396

Let's proceed to step 5:
When dividing 1771 by 396, we get 4 with a remainder of 187.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 1584 from 1771 and we're left with 187.
Bring next digit (0) of the dividend behind the 187 and repeat the process: 1870 / 396

Advancing to step 6:
1870 divided by 396 is 4 with a remainder of 286.
The next digit of our result is 4. 
Result so far: 1444.0
If we take 1584 away from 1870, we end up with 286.
Take the next digit (9) from the dividend and append it to 286, then repeat: 2869 / 396

Moving on to step 7:
When dividing 2869 by 396, we get 7 with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 14447.0
Subtracting 2772 from 2869 leaves us with 97.
Fetch the next digit (0) from the dividend, attach it to 97 and continue: 970 / 396

Moving on to step 8:
The number 396 fits into 970 2 times, leaving a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 144472.0
If we take 792 away from 970, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 9:
If we divide 1780 by 396, we get 4 and a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 144472.4
The remainder is 196 after subtracting 1584 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
When dividing 1960 by 396, we get 4 with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 144472.44
Subtracting 1584 from 1960 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 144472.44 with a remainder of 0.376.
