We're dividing 51660 by 9 
Our goal is to divide 51660 by 9.

Advancing to step 1:
5 divided by 9 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 9

Advancing to step 2:
If we divide 51 by 9, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 45 from 51 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 9

Going ahead to step 3:
9 can be fit into 66 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 63 from 66 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

Let's proceed to step 4:
36 divided by 9 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 574.0
Deduct 36 from 36 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Going ahead to step 5:
0 divided by 9 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5740.0
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.

Step 6:
When dividing 0 by 9, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5740.0
If we take 0 away from 0, we end up 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.

On to step 7:
9 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5740.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5740.0 with a remaining 0.0.
