980288 divided by 13 
We're looking to find how many times 13 goes into 980288.

Going ahead to step 1:
When dividing 9 by 13, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 13

On to step 2:
If we divide 98 by 13, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 13

Advancing to step 3:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we take 65 away from 70, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 13

Let's proceed to step 4:
13 goes into 52 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 754.0
Subtract 52 from 52 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 13

On to step 5:
8 divided by 13 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 7540.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

On to step 6:
If we divide 88 by 13, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 75406.0
If we subtract 78 from 88, 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 7:
If we divide 100 by 13, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 75406.7
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 8:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 75406.76
Subtract 78 from 90 to 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.

On to step 9:
If we divide 120 by 13, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 75406.769
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.

Step 10:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 75406.7692
The remainder is 4 after subtracting 26 from 30.
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:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 75406.76923
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.

On to step 12:
When dividing 10 by 13, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 75406.76923
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.

Moving on to step 13:
100 divided by 13 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 75406.7692307
Subtract 91 from 100 to 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.

Moving on to step 14:
13 goes into 90 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 75406.76923076
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.

The final outcome is 75406.76923076, with a leftover of 1.2e-08.
