We look at the division of 384431 by 77 
We want to figure out the number of times 384431 can be divided by 77.

Moving on to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 77

Step 2:
77 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 77

Let's proceed to step 3:
When dividing 384 by 77, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 308 away from 384, we end up with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 77

On to step 4:
77 can be fit into 764 9 times, resulting in a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 693 from 764 leaves us with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 77

Step 5:
77 goes into 713 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 499.0
If we subtract 693 from 713, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 77

Moving on to step 6:
If we divide 201 by 77, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 4992.0
Deduct 154 from 201 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
The number 77 fits into 470 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4992.6
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 77 fits into 80 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 4992.61
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 77 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4992.61
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 77 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 4992.6103
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 11:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 4992.61038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 4992.610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
The number 77 fits into 470 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4992.6103896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
80 divided by 77 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4992.61038961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 4992.61038961 with a remaining 3e-09.
