168550 divided by 66 
We want to figure out the number of times 168550 can be divided by 66.

Step 1:
1 divided by 66 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 66

Moving on 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
The remainder is 16 after subtracting 0 from 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 66

Let's proceed to step 3:
The number 66 fits into 168 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 132 from 168 and we're left with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 66

Moving on to step 4:
The number 66 fits into 365 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 35 after subtracting 330 from 365.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 66

Step 5:
355 divided by 66 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 255.0
If we subtract 330 from 355, we get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 66

Advancing to step 6:
When dividing 250 by 66, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 2553.0
Deduct 198 from 250 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
66 goes into 520 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 2553.7
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
If we divide 580 by 66, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 2553.78
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 2553.787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
When dividing 580 by 66, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 2553.7878
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 66, we get 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 2553.78787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
The number 66 fits into 580 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 2553.787878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
If we divide 520 by 66, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 2553.7878787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
When dividing 580 by 66, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 2553.78787878
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 2553.78787878, with a leftover of 5.2e-08.
