392548 ÷ 77 
We want to divide 392548 by 77.

Moving on to step 1:
When dividing 3 by 77, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 77

On to step 2:
77 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 77

Let's proceed to step 3:
77 goes into 392 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 7 after subtracting 385 from 392.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 77

Going ahead to step 4:
If we divide 75 by 77, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 77

Advancing to step 5:
754 divided by 77 is 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 509.0
If we subtract 693 from 754, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 77

Step 6:
618 divided by 77 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 5098.0
If we subtract 616 from 618, 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.

Step 7:
77 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5098.0
If we subtract 0 from 20, we 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.

Advancing to step 8:
77 can be fit into 200 2 times, resulting in a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 5098.02
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
77 can be fit into 460 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 5098.025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
If we divide 750 by 77, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 5098.0259
If we take 693 away from 750, we end up 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 11:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 5098.02597
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.

Let's proceed to step 12:
If we divide 310 by 77, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 5098.025974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
77 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 5098.025974
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 77, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 5098.02597402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 5098.02597402, with a leftover of 4.6e-08.
