We're dividing 768690 by 66 
Our goal is to divide 768690 by 66.

Step 1:
66 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 66

Step 2:
When dividing 76 by 66, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 76, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 66

Let's proceed to step 3:
108 divided by 66 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 66 away from 108, we end up with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 66

Going ahead to step 4:
66 goes into 426 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 30 after subtracting 396 from 426.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 66

Let's proceed to step 5:
309 divided by 66 is 4 with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 1164.0
If we subtract 264 from 309, we get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 66

Let's proceed to step 6:
66 goes into 450 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 11646.0
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
66 goes into 540 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 11646.8
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
66 goes into 120 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 11646.81
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
540 divided by 66 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 11646.818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 11646.8181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
66 goes into 540 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 11646.81818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 11646.818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
540 divided by 66 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11646.8181818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
66 goes into 120 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 11646.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 11646.81818181 and a remainder of 5.4e-08.
