We divide 390637 by 13
Let's see how many times 13 fits into 390637.

Let's proceed to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 13

Advancing to step 2:
If we divide 39 by 13, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 39 from 39.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 13

On to step 3:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 13

Going ahead to step 4:
When dividing 6 by 13, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 13

Going ahead to step 5:
When dividing 63 by 13, we get 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 3004.0
Deduct 52 from 63 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 13

Advancing to step 6:
If we divide 117 by 13, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 30049.0
If we take 117 away from 117, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 13, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 30049.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
13 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30049.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 30049.0 and a remainder of 0.0.
