189003 ÷ 66 
Let's see how many times 66 fits into 189003.

Let's proceed to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 66

Advancing to step 2:
The number 66 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 66

Moving on to step 3:
When dividing 189 by 66, we get 2 with a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 57 after subtracting 132 from 189.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 66

Moving on to step 4:
The number 66 fits into 570 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 42 after subtracting 528 from 570.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 66

Moving on to step 5:
The number 66 fits into 420 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
Subtracting 396 from 420 leaves us with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 66

Going ahead to step 6:
66 goes into 243 3 times with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 2863.0
Subtract 198 from 243 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
66 goes into 450 6 times with a remainder of 54.
The next digit of our result is 6. 
Result so far: 2863.6
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 66, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2863.68
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 66, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 2863.681
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2863.6818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 66 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 2863.68181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
The number 66 fits into 540 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 2863.681818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 2863.6818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
540 divided by 66 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 2863.68181818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 2863.68181818, with a leftover of 1.2e-08.
