864070 ÷ 66 
Our goal is to divide 864070 by 66.

Let's proceed to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 66

Advancing to step 2:
66 can be fit into 86 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 86, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 66

Going ahead to step 3:
66 can be fit into 204 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 198 from 204 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 66

Going ahead to step 4:
When dividing 60 by 66, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 66

Advancing to step 5:
607 divided by 66 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 1309.0
Deduct 594 from 607 and we're left with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 66

Let's proceed to step 6:
130 divided by 66 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 13091.0
Deduct 66 from 130 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.

Step 7:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 13091.9
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.

Let's proceed to step 8:
460 divided by 66 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 13091.96
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.

Step 9:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 13091.969
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.

Moving on to step 10:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 13091.9696
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.

On to step 11:
When dividing 640 by 66, we get 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 13091.96969
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.

Step 12:
If we divide 460 by 66, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 13091.969696
Subtract 396 from 460 to 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.

Going ahead to step 13:
When dividing 640 by 66, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 13091.9696969
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.

Moving on to step 14:
460 divided by 66 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 13091.96969696
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.

The final result is 13091.96969696 with a remainder of 6.4e-08.
