Let's divide 169666 by 66
Our goal is to divide 169666 by 66.

Step 1:
1 divided by 66 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 66

Step 2:
16 divided by 66 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 66

On to step 3:
The number 66 fits into 169 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 132 from 169 to get 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 66

Advancing to step 4:
If we divide 376 by 66, we get 5 and a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 330 from 376 and we're left with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 66

Moving on to step 5:
66 goes into 466 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
The remainder is 4 after subtracting 462 from 466.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 66

Let's proceed to step 6:
46 divided by 66 is 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 2570.0
The remainder is 46 after subtracting 0 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
66 goes into 460 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 2570.6
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 2570.69
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
If we divide 460 by 66, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 2570.696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 2570.6969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
If we divide 460 by 66, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 2570.69696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 2570.696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 2570.6969696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
When dividing 640 by 66, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 2570.69696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 2570.69696969 with a balance of 4.6e-08.
