11577 ÷ 51 
We want to divide 11577 by 51.

On to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 51

Going ahead to step 2:
The number 51 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 51

Let's proceed to step 3:
The number 51 fits into 115 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we take 102 away from 115, we end up with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 51

Step 4:
If we divide 137 by 51, we get 2 and a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 102 from 137 leaves us with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 51

Advancing to step 5:
51 goes into 357 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 227.0
The remainder is 0 after subtracting 357 from 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
The number 51 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 227.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
51 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 227.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 227.0 with a remainder of 0.0.
