We divide 386378 by 99
Our goal is to divide 386378 by 99.

On to step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 99

Step 2:
99 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 99

On to step 3:
If we divide 386 by 99, we get 3 and a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 297 from 386 leaves us with 89.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 99

Let's proceed to step 4:
When dividing 893 by 99, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 39.0
If we take 891 away from 893, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 99

Moving on to step 5:
99 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 390.0
If we subtract 0 from 27, we get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 99

Going ahead to step 6:
If we divide 278 by 99, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 3902.0
Subtracting 198 from 278 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 7:
When dividing 800 by 99, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3902.8
Deduct 792 from 800 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.

On to step 8:
When dividing 80 by 99, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3902.8
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 99, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3902.808
Subtracting 792 from 800 leaves us 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.

Step 10:
80 divided by 99 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3902.808
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
99 goes into 800 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3902.80808
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3902.80808
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 99 fits into 800 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3902.8080808
If we take 792 away from 800, 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.

Step 14:
99 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3902.8080808
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 3902.8080808 with a remainder of 8e-08.
