Let's divide 859766 by 66
We want to divide 859766 by 66.

Advancing to step 1:
8 divided by 66 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 66

Step 2:
66 can be fit into 85 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 66 away from 85, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 66

Let's proceed to step 3:
When dividing 199 by 66, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 198 from 199 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 66

Moving on to step 4:
66 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we subtract 0 from 17, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 66

Going ahead to step 5:
When dividing 176 by 66, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1302.0
Deduct 132 from 176 and we're left with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 66

Moving on to step 6:
66 can be fit into 446 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 13026.0
If we subtract 396 from 446, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
66 goes into 500 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 13026.7
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 66, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 13026.75
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
66 goes into 500 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 13026.757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
66 goes into 380 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 13026.7575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 66 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 13026.75757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 66 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 13026.757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 13026.7575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
When dividing 380 by 66, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 13026.75757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 13026.75757575 and a remainder of 5e-08.
