859825 ÷ 66 
Let's see how many times 66 fits into 859825.

Moving on 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
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 66

On to step 2:
If we divide 85 by 66, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 66 from 85 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 66

On to step 3:
66 goes into 199 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 1 after subtracting 198 from 199.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 66

Going ahead to step 4:
18 divided by 66 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 66

Let's proceed to step 5:
When dividing 182 by 66, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 1302.0
Subtracting 132 from 182 leaves us with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 66

Step 6:
When dividing 505 by 66, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 13027.0
Deduct 462 from 505 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
If we divide 430 by 66, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 13027.6
Subtract 396 from 430 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
If we divide 340 by 66, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 13027.65
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 13027.651
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
When dividing 340 by 66, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 13027.6515
Deduct 330 from 340 and we're left 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.

Advancing to step 11:
66 goes into 100 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 13027.65151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
340 divided by 66 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13027.651515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 66 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 13027.6515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
The number 66 fits into 340 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13027.65151515
Deduct 330 from 340 and we're left 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.

The final result is 13027.65151515 with a remainder of 1e-08.
