We're dividing 386238 by 77 
We want to figure out the number of times 386238 can be divided by 77.

Let's proceed to step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 77

Let's proceed to step 2:
77 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 77

Step 3:
The number 77 fits into 386 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 385 from 386, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 77

Let's proceed to step 4:
77 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 77

Going ahead to step 5:
77 goes into 123 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 501.0
Deduct 77 from 123 and we're left with 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 77

Advancing to step 6:
The number 77 fits into 468 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 5016.0
Subtracting 462 from 468 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 77, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5016.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
77 goes into 600 7 times with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 5016.07
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
If we divide 610 by 77, we get 7 and a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 5016.077
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 5016.077 with a remainder of 0.0071.
