We're dividing 378009 by 99 
We're looking to find how many times 99 goes into 378009.

Let's proceed to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 99

Going ahead to step 2:
When dividing 37 by 99, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 99

Advancing to step 3:
If we divide 378 by 99, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 297 from 378 leaves us with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 99

Going ahead to step 4:
The number 99 fits into 810 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 792 from 810 to get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 99

Advancing to step 5:
180 divided by 99 is 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 381.0
Subtracting 99 from 180 leaves us with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 99

On to step 6:
When dividing 819 by 99, we get 8 with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 3818.0
If we subtract 792 from 819, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 99 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 3818.2
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
99 goes into 720 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3818.27
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
When dividing 270 by 99, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 3818.272
The remainder is 72 after subtracting 198 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
99 goes into 720 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3818.2727
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
If we divide 270 by 99, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 3818.27272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
99 goes into 720 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 3818.272727
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
99 goes into 270 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 3818.2727272
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
720 divided by 99 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 3818.27272727
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 3818.27272727 with a remaining 2.7e-08.
