We divide 165993 by 66
Let's see how many times 66 fits into 165993.

Going ahead to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 66

Going ahead to step 2:
16 divided by 66 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 66

Advancing to step 3:
165 divided by 66 is 2 with a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 33 after subtracting 132 from 165.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 66

On to step 4:
66 goes into 339 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 330 away from 339, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 66

Let's proceed to step 5:
66 can be fit into 99 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 251.0
The remainder is 33 after subtracting 66 from 99.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 66

Advancing to step 6:
66 can be fit into 333 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 2515.0
Deduct 330 from 333 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 66, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 2515.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2515.04
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 66, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 2515.045
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 2515.0454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2515.04545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 66 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2515.045454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2515.0454545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
If we divide 300 by 66, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 2515.04545454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 2515.04545454 with a balance of 3.6e-08.
