We look at the division of 666945 by 77 
We want to divide 666945 by 77.

Moving on to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 77

Going ahead to step 2:
66 divided by 77 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 77

Let's proceed to step 3:
When dividing 666 by 77, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 616 away from 666, we end up with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 77

Advancing to step 4:
When dividing 509 by 77, we get 6 with a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 462 from 509 and we're left with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 77

Let's proceed to step 5:
77 can be fit into 474 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 866.0
The remainder is 12 after subtracting 462 from 474.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 77

Moving on to step 6:
125 divided by 77 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 8661.0
The remainder is 48 after subtracting 77 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 77, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 8661.6
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 77, we get 2 and a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 8661.62
The remainder is 26 after subtracting 154 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
260 divided by 77 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 8661.623
The remainder is 29 after subtracting 231 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
290 divided by 77 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 8661.6233
If we subtract 231 from 290, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

In conclusion, the division gives 8661.6233 with a balance of 0.00059.
