We're dividing 855023 by 66 
We want to figure out the number of times 855023 can be divided by 66.

Let's proceed to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 66

Moving on to step 2:
66 can be fit into 85 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 66 from 85 leaves us with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 66

Step 3:
If we divide 195 by 66, we get 2 and a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 132 from 195 leaves us with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 66

Step 4:
66 goes into 630 9 times with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we subtract 594 from 630, we get 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 66

On to step 5:
362 divided by 66 is 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 1295.0
Subtracting 330 from 362 leaves us with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 66

Step 6:
66 goes into 323 4 times with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 12954.0
Deduct 264 from 323 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
When dividing 590 by 66, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 12954.8
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 12954.89
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
When dividing 260 by 66, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 12954.893
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 12954.8939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 12954.89393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
66 goes into 620 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 12954.893939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
260 divided by 66 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 12954.8939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
620 divided by 66 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 12954.89393939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 12954.89393939 with a remainder of 2.6e-08.
