865613 ÷ 66 
Let's see how many times 66 fits into 865613.

Moving on to step 1:
8 divided by 66 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 66

Advancing to step 2:
If we divide 86 by 66, we get 1 and 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.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 66

Moving on to step 3:
If we divide 205 by 66, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 198 from 205 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 66

Moving on to step 4:
When dividing 76 by 66, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we subtract 66 from 76, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 66

Moving on to step 5:
The number 66 fits into 101 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1311.0
If we subtract 66 from 101, we get 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 66

Moving on to step 6:
If we divide 353 by 66, we get 5 and a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 13115.0
The remainder is 23 after subtracting 330 from 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
66 goes into 230 3 times with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 13115.3
Deduct 198 from 230 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 66 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 13115.34
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 13115.348
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 66, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 13115.3484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 13115.34848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
66 goes into 320 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 13115.348484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
560 divided by 66 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13115.3484848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 13115.34848484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 13115.34848484 with a balance of 5.6e-08.
