858666 divided by 65 
We want to figure out the number of times 858666 can be divided by 65.

Step 1:
8 divided by 65 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 65

Advancing to step 2:
65 can be fit into 85 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 65 from 85 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 65

Going ahead to step 3:
65 goes into 208 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 13.0
If we take 195 away from 208, we end up with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 65

Moving on to step 4:
The number 65 fits into 136 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 130 from 136 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 65

On to step 5:
66 divided by 65 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1321.0
Subtracting 65 from 66 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 65

Moving on to step 6:
When dividing 16 by 65, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 13210.0
If we take 0 away from 16, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
65 goes into 160 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 13210.2
Deduct 130 from 160 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 65, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 13210.24
Deduct 260 from 300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
65 goes into 400 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 13210.246
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 65 is 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 13210.2461
Deduct 65 from 100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
65 goes into 350 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 13210.24615
Deduct 325 from 350 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
When dividing 250 by 65, we get 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 13210.246153
The remainder is 55 after subtracting 195 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
If we divide 550 by 65, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 13210.2461538
If we take 520 away from 550, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 13210.24615384
Subtracting 260 from 300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 13210.24615384 with a balance of 4e-08.
