We look at the division of 423830 by 77 
We want to divide 423830 by 77.

Advancing to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 77

Advancing to step 2:
42 divided by 77 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 77

On to step 3:
If we divide 423 by 77, we get 5 and a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 38 after subtracting 385 from 423.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 77

Step 4:
The number 77 fits into 388 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we take 385 away from 388, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 77

Let's proceed to step 5:
The number 77 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 550.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 77

Advancing to step 6:
77 can be fit into 330 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 5504.0
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
77 goes into 220 2 times with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 5504.2
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
660 divided by 77 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 5504.28
Subtracting 616 from 660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
77 can be fit into 440 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5504.285
If we subtract 385 from 440, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
When dividing 550 by 77, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 5504.2857
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
110 divided by 77 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 5504.28571
If we take 77 away from 110, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
If we divide 330 by 77, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 5504.285714
Deduct 308 from 330 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
If we divide 220 by 77, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 5504.2857142
Subtract 154 from 220 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
77 can be fit into 660 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 5504.28571428
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 5504.28571428 with a balance of 4.4e-08.
