3890873 ÷ 13 
Let's see how many times 13 fits into 3890873.

Let's proceed to step 1:
13 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 13

Moving on to step 2:
If we divide 38 by 13, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 12 after subtracting 26 from 38.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 13

Moving on to step 3:
13 goes into 129 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 117 away from 129, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 13

Moving on to step 4:
When dividing 120 by 13, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 299.0
Subtracting 117 from 120 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 13

Let's proceed to step 5:
If we divide 38 by 13, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2992.0
If we take 26 away from 38, we end up with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 13

Let's proceed to step 6:
The number 13 fits into 127 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 29929.0
Subtracting 117 from 127 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 13

Step 7:
The number 13 fits into 103 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 299297.0
If we take 91 away from 103, we end up 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.

Advancing to step 8:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 299297.9
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
13 goes into 30 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 299297.92
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 13, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 299297.923
If we subtract 39 from 40, we 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.

Moving on to step 11:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 299297.923
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.

On to step 12:
13 goes into 100 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 299297.92307
The remainder is 9 after subtracting 91 from 100.
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 13:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 299297.923076
If we take 78 away from 90, we end up 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.

Step 14:
120 divided by 13 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 299297.9230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 299297.92307692
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 299297.92307692, and the remainder is 4e-09.
