We're dividing 78022388 by 387 
We want to divide 78022388 by 387.

Let's proceed to step 1:
If we divide 7 by 387, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 387

Going ahead to step 2:
The number 387 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 387

Moving on to step 3:
387 goes into 780 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 774 from 780, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 387

Step 4:
387 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 62, we get 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 387

On to step 5:
The number 387 fits into 622 1 times, leaving a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 201.0
The remainder is 235 after subtracting 387 from 622.
Append the next digit (3) from the dividend to 235 and continue with: 2353 / 387

Going ahead to step 6:
387 goes into 2353 6 times with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 2016.0
If we subtract 2322 from 2353, we get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 387

Advancing to step 7:
318 divided by 387 is 0 with a remainder of 318.
The number 0 becomes the next digit in our result. 
Result so far: 20160.0
Subtract 0 from 318 to get 318.
Include the next digit (8) from the dividend after 318, then repeat: 3188 / 387

Moving on to step 8:
387 goes into 3188 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 201608.0
If we take 3096 away from 3188, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 9:
387 goes into 920 2 times with a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 201608.2
If we take 774 away from 920, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
387 can be fit into 1460 3 times, resulting in a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 201608.23
Deduct 1161 from 1460 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 11:
The number 387 fits into 2990 7 times, leaving a remainder of 281.
Use 7 as the next digit of our solution. 
Result so far: 201608.237
Subtracting 2709 from 2990 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 12:
387 can be fit into 2810 7 times, resulting in a remainder of 101.
The next digit of our result is 7. 
Result so far: 201608.2377
The remainder is 101 after subtracting 2709 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 201608.2377, with a leftover of 0.00101.
