We're dividing 865471 by 66 
Let's see how many times 66 fits into 865471.

Step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 66

On to step 2:
If we divide 86 by 66, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 66 from 86 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 66

Moving on to step 3:
66 can be fit into 205 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 198 from 205 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 66

Let's proceed to step 4:
74 divided by 66 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 131.0
The remainder is 8 after subtracting 66 from 74.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 66

Going ahead to step 5:
87 divided by 66 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1311.0
If we take 66 away from 87, we end up with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 66

Going ahead to step 6:
The number 66 fits into 211 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 13113.0
Subtract 198 from 211 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 66, we get 1 with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 13113.1
If we subtract 66 from 130, we get 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:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 13113.19
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.

Going ahead to step 9:
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: 13113.196
If we subtract 396 from 460, we get 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: 13113.1969
If we subtract 594 from 640, we 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.

On to step 11:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13113.19696
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.

Going ahead to step 12:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 13113.196969
If we subtract 594 from 640, we 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.

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: 13113.1969696
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.

Advancing to step 14:
66 goes into 640 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 13113.19696969
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.

After the division, we end up with 13113.19696969 and a remainder of 4.6e-08.
