We divide 378990 by 13
We want to divide 378990 by 13.

Step 1:
13 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 13

Going ahead to step 2:
13 goes into 37 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 26 from 37 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 13

Let's proceed to step 3:
13 can be fit into 118 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 117 away from 118, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 13

Let's proceed to step 4:
13 goes into 19 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 291.0
The remainder is 6 after subtracting 13 from 19.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 13

Step 5:
The number 13 fits into 69 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 2915.0
If we take 65 away from 69, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 13

Going ahead to step 6:
When dividing 40 by 13, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 29153.0
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 29153.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 29153.07
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 29153.076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 29153.0769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 13, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29153.07692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
13 goes into 40 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 29153.076923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 29153.076923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 29153.07692307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 29153.07692307 with a balance of 9e-09.
