Let's divide 977143 by 77
Our goal is to divide 977143 by 77.

Going ahead to step 1:
77 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 77

Going ahead to step 2:
97 divided by 77 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 97, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 77

Advancing to step 3:
When dividing 207 by 77, we get 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 53 after subtracting 154 from 207.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 77

On to step 4:
The number 77 fits into 531 6 times, leaving a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtract 462 from 531 to get 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 77

Step 5:
If we divide 694 by 77, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1269.0
If we subtract 693 from 694, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 77

Step 6:
77 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 12690.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 77 is 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 12690.1
If we take 77 away from 130, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
77 goes into 530 6 times with a remainder of 68.
The next digit of our result is 6. 
Result so far: 12690.16
If we take 462 away from 530, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
77 goes into 680 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 12690.168
Subtracting 616 from 680 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12690.1688
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 12690.1688 and a remainder of 0.00024.
