We look at the division of 10395150 by 378 
Our goal is to divide 10395150 by 378.

Let's proceed to step 1:
When dividing 1 by 378, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 378

Going ahead to step 2:
If we divide 10 by 378, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 378

Advancing to step 3:
If we divide 103 by 378, we get 0 and a remainder of 103.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 103 leaves us with 103.
Append the next digit (9) from the dividend to 103 and continue with: 1039 / 378

On to step 4:
When dividing 1039 by 378, we get 2 with a remainder of 283.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 756 from 1039 and we're left with 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 378

On to step 5:
2835 divided by 378 is 7 with a remainder of 189.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 2646 from 2835, we get 189.
Grab the next digit (1) from the dividend, add it to 189, then carry on: 1891 / 378

Let's proceed to step 6:
The number 378 fits into 1891 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 275.0
If we take 1890 away from 1891, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 378

Let's proceed to step 7:
15 divided by 378 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 2750.0
Subtract 0 from 15 to get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 378

Step 8:
150 divided by 378 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 27500.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
When dividing 1500 by 378, we get 3 with a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 27500.3
Subtracting 1134 from 1500 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 10:
378 can be fit into 3660 9 times, resulting in a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 27500.39
Subtract 3402 from 3660 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 11:
The number 378 fits into 2580 6 times, leaving a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 27500.396
If we subtract 2268 from 2580, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
If we divide 3120 by 378, we get 8 and a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 27500.3968
If we take 3024 away from 3120, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
378 can be fit into 960 2 times, resulting in a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 27500.39682
Subtract 756 from 960 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 14:
When dividing 2040 by 378, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 27500.396825
Deduct 1890 from 2040 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
378 can be fit into 1500 3 times, resulting in a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 27500.3968253
If we take 1134 away from 1500, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 16:
378 can be fit into 3660 9 times, resulting in a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 27500.39682539
The remainder is 258 after subtracting 3402 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final result is 27500.39682539 with a remainder of 2.58e-07.
