We look at the division of 189965 by 66 
We want to figure out the number of times 189965 can be divided by 66.

Going ahead to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 66

Step 2:
66 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 66

Going ahead to step 3:
The number 66 fits into 189 2 times, leaving a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 132 from 189 and we're left with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 66

Going ahead to step 4:
The number 66 fits into 579 8 times, leaving a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 528 from 579 leaves us with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 66

Step 5:
66 can be fit into 516 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 287.0
Deduct 462 from 516 and we're left with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 66

Moving on to step 6:
66 can be fit into 545 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 2878.0
The remainder is 17 after subtracting 528 from 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 66 fits into 170 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2878.2
Deduct 132 from 170 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
66 goes into 380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2878.25
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2878.257
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
66 can be fit into 380 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 2878.2575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2878.25757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2878.257575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
500 divided by 66 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 2878.2575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
If we divide 380 by 66, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2878.25757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 2878.25757575 with a balance of 5e-08.
