438660 ÷ 77 
We want to divide 438660 by 77.

Going ahead to step 1:
4 divided by 77 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 77

Advancing to step 2:
77 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 77

Moving on to step 3:
438 divided by 77 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 385 from 438, we get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 77

Let's proceed to step 4:
When dividing 536 by 77, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 462 from 536, we get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 77

Step 5:
When dividing 746 by 77, we get 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 569.0
If we subtract 693 from 746, we get 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 77

Moving on to step 6:
The number 77 fits into 530 6 times, leaving a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 5696.0
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.

Going ahead to step 7:
The number 77 fits into 680 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 5696.8
If we take 616 away from 680, we end up 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 8:
77 can be fit into 640 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 5696.88
Subtract 616 from 640 to get 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 5696.88 and a remainder of 0.024.
