Let's divide 855109 by 66
We're looking to find how many times 66 goes into 855109.

Advancing to step 1:
66 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 66

Going ahead to step 2:
85 divided by 66 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 85 and we're left with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 66

Moving on to step 3:
66 goes into 195 2 times with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 132 from 195 leaves us with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 66

Going ahead to step 4:
66 can be fit into 631 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Deduct 594 from 631 and we're left with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 66

Advancing to step 5:
66 goes into 370 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1295.0
Subtracting 330 from 370 leaves us with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 66

Step 6:
409 divided by 66 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 12956.0
The remainder is 13 after subtracting 396 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
66 can be fit into 130 1 times, resulting in a remainder of 64.
The next digit of our result is 1. 
Result so far: 12956.1
If we take 66 away from 130, 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.

Moving on to step 8:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 12956.19
If we take 594 away from 640, we end up 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 9:
66 goes into 460 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 12956.196
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.

Going ahead to step 10:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 12956.1969
If we take 594 away from 640, we end up 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.

On to step 11:
66 goes into 460 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 12956.19696
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.

Going ahead to step 12:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 12956.196969
Subtracting 594 from 640 leaves us 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.

Moving on to step 13:
460 divided by 66 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 12956.1969696
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 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: 12956.19696969
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.

Our division results in 12956.19696969 with a remaining 4.6e-08.
