980405 ÷ 13 
We want to divide 980405 by 13.

On to step 1:
13 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 13

Let's proceed to step 2:
When dividing 98 by 13, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 13

On to step 3:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 75.0
If we take 65 away from 70, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 13

Moving on to step 4:
13 can be fit into 54 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 754.0
Deduct 52 from 54 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 13

Let's proceed to step 5:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 7541.0
If we subtract 13 from 20, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 13

Moving on to step 6:
13 can be fit into 75 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 75415.0
Deduct 65 from 75 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.

Going ahead to step 7:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 75415.7
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 75415.76
If we subtract 78 from 90, we get 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 9:
13 goes into 120 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 75415.769
Subtracting 117 from 120 leaves us 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 10:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 75415.7692
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.

Going ahead to step 11:
13 goes into 40 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 75415.76923
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.

Going ahead to step 12:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 75415.76923
If we subtract 0 from 10, we get 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 13:
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: 75415.7692307
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.

Step 14:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 75415.76923076
Subtracting 78 from 90 leaves us 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.

The final outcome is 75415.76923076, with a leftover of 1.2e-08.
