We look at the division of 13235091 by 378 
Let's see how many times 378 fits into 13235091.

Let's proceed to step 1:
378 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 378

Advancing to step 2:
378 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 378

Moving on to step 3:
When dividing 132 by 378, we get 0 with a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 132, we get 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 378

Going ahead to step 4:
When dividing 1323 by 378, we get 3 with a remainder of 189.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1134 away from 1323, we end up with 189.
Append the next digit (5) from the dividend to 189 and continue with: 1895 / 378

Step 5:
378 can be fit into 1895 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 1890 from 1895 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 378

Step 6:
378 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 378

Step 7:
If we divide 509 by 378, we get 1 and a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 3501.0
If we subtract 378 from 509, we get 131.
Fetch the next digit (1) from the dividend, attach it to 131 and continue: 1311 / 378

Going ahead to step 8:
1311 divided by 378 is 3 with a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 35013.0
If we take 1134 away from 1311, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
When dividing 1770 by 378, we get 4 with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 35013.4
If we take 1512 away from 1770, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 10:
378 can be fit into 2580 6 times, resulting in a remainder of 312.
Put 6 as the next digit of the answer. 
Result so far: 35013.46
Subtract 2268 from 2580 to 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.

On to step 11:
378 goes into 3120 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 35013.468
If we subtract 3024 from 3120, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
The number 378 fits into 960 2 times, leaving a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 35013.4682
If we take 756 away from 960, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 13:
When dividing 2040 by 378, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 35013.46825
Subtract 1890 from 2040 to 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 14:
When dividing 1500 by 378, we get 3 with a remainder of 366.
Record the quotient 3 as the next digit in the result. 
Result so far: 35013.468253
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.

Moving on to step 15:
If we divide 3660 by 378, we get 9 and a remainder of 258.
Use 9 as the next digit of our solution. 
Result so far: 35013.4682539
Deduct 3402 from 3660 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 16:
If we divide 2580 by 378, we get 6 and a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 35013.46825396
Deduct 2268 from 2580 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 35013.46825396 with a remainder of 3.12e-07.
