We're dividing 663540 by 77 
Our goal is to divide 663540 by 77.

Going ahead to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 77

Advancing to step 2:
77 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 77

Let's proceed to step 3:
663 divided by 77 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 616 from 663 to get 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 77

Advancing to step 4:
475 divided by 77 is 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 462 from 475 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 77

Moving on to step 5:
If we divide 134 by 77, we get 1 and a remainder of 57.
The next digit of our result is 1. 
Result so far: 861.0
If we subtract 77 from 134, we get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 77

Let's proceed to step 6:
If we divide 570 by 77, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 8617.0
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
If we divide 310 by 77, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 8617.4
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8617.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 77, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 8617.402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
460 divided by 77 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8617.4025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
When dividing 750 by 77, we get 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 8617.40259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
570 divided by 77 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 8617.402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 8617.4025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
When dividing 20 by 77, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8617.4025974
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 8617.4025974 with a balance of 2e-08.
